1 Introduction

Since the dawn of the nuclear age access to the most recent nuclear dataplayed a crucial role in nuclear physics research and application develop-ment These data were originally disseminated as paper copies for designatedusers and eventually evolved into the present-day computer files distributedover the World Wide Web The National Nuclear Data Center (NNDC)Brookhaven National Laboratory (BNL) and Nuclear Data Section (NDS)International Atomic Energy Agency (IAEA) have always been pioneers innuclear data collection evaluation and dissemination They have been pro-viding remote electronic access to their databases and other information since1986 In this work the authors will concentrate on the present state of storageanalysis and worldwide distribution of low- and intermediate-energy nuclearreaction data

EXFOR experimental nuclear reaction database [1 2] is the worldrsquos primerepository for reaction data compilations The EXFOR library was estab-lished in 1967 at a meeting of the four major nuclear data centers BrookhavenNational Laboratory Upton NY (Area 1 USA Canada) Nuclear EnergyAgency (NEA) Databank Paris France (Area 2 Western Europe andJapan) International Atomic Energy Agency Vienna Austria (Area 3Asia Eastern Europe Latin America Africa Australia and Oceania) andInstitute of Physics and Power Engineering (IPPE) Obninsk USSR (Area4 Soviet Union) [1] This project was based on previously-existing ef-forts such as the NNDC predecessorrsquos Sigma Center Information Storageand Retrieval System (SCISRS) and the associated format Currently theEXFOR project is an international collaboration under the auspices of theInternational Atomic Energy Agency and 13 nuclear data centers from theUSA OECDData Bank (France) IAEANDS (Austria) Russian Federa-tion China Hungary India Japan Kazakhstan Korea and Ukraine regu-larly contribute to it

Figure 1 Content evolution of the EXFOR database Neutron reactions have been com-piled systematically since the initiation of the EXFOR project while charged particle andphoton (gamma) reactions have been covered less extensively Complementary details areavailable in Ref [3]

alpha- and photon-induced reactions constitute 479 198 736 and 62 ofdatabase contents respectively The historic evolution of EXFOR contentsis shown in Fig 1 In addition to cross section data the EXFOR libraryincludes information on incoming particle spectra such as 252Cf spontaneousfission and β-delayed neutrons Heavy ion- electron- and pion-induced reac-tions with energies up to 1 GeV are compiled by the responsible centers ona voluntary basis

The present database is the largest low- and intermediate-energy nuclearreaction library as of November 27 2017 it includes 21885 experiments170088 data sets and 15213129 data points The database contains infor-mation on 968 targets 386 incident projectiles and 2606 nuclear reactionsTo further illustrate the volume and diversity of the database and associatedcomputer programming challenges we will provide a list of compiled nuclearphysics quantities in Table 1 The table data show that cross section datasets represent approximately half of the database contents It also includessubstantial contributions from differential data with respect to angle par-tial cross sections resonance parameters polarization data fission product

yields and double differential cross section measurements The total numberof Table 1 compilations exceeds the overall number of experiments due to acomplex structure of compiled entries a single entry often contains multipledata subentries reaction strings and reaction combinations

Figure 1 data highlight the fact that neutron-induced reactions represent abackbone of EXFOR and these data are essential for many applications Theneutron reactions constitute a perfect case of mutually-beneficial relationsbetween the fundamental and applied sciences For demonstration purposesthe authors will analyze neutron capture and inverse photoneutron reactionsand the historical evolution of experimental nuclear reaction activities Thesedirect and inverse reactions play an essential role in computer modeling ofastrophysical s r and p processes and they are crucial in nuclear reactorcalculations Data shown in the left panels of Fig 2 demonstrate that themost frequently-used neutron capture targets are gold (Au) uranium (U)and tin (Sn) while neutron-rich tin gold and uranium are materials of choicefor photo-neutron reaction studies Subsequent examination of the rightpanels provides indication of two trends large numbers of nuclear reactionmeasurements in the 1970rsquos [3] and a recent increase in number of (nγ) and(γn) reactions Further analysis of the last finding reveals a substantialcontribution of Maxwellian-averaged cross section measurements in recentyears These experiments tackle nuclear astrophysics problems and providecomplementary benchmarks for nuclear reactor modeling

21 EXFOR Data Compilation

In the early 1950rsquos data compilations have been pioneered at the BrookhavenNational Laboratory in support of nuclear science and reactor research ac-tivities [1 4] Since 1964 Brookhaven compilations have been stored in theSCISRS computer system that predated the EXFOR database These exper-imental data compilation efforts have always had an important internationalcomponent The IAEA Nuclear Data Section has been involved in this worksince its creation in 1964 Other early contributors include NEA Data BankParis France and the Institute of Physics and Power Engineering ObninskUSSR which were founded in 1964 and 1963 respectively [1] In 1969 anagreement on an exchange format was reached between four centers and July1970 was chosen as the starting date for transmission of neutron data be-tween the partners in the EXFOR format The effort to translate all of theexisting experimental nuclear reaction data sets which were coded in theSCISRS system format would be done later [1]

Figure 2 EXFOR compilations of nuclear astrophysics relevant neutron capture (nγ) andphoto-neutron (γn) production reactions vs target material (z) and historical distribu-tion of experimental results are shown in left and right panels respectively

In recent years the EXFOR compilations became even more popularworldwide and a large number of institutions have joined In fact EXFORrepresents one of the oldest continuously-operated scientific collaborationsSince its creation the EXFOR project has relied heavily on computer tech-nologies available at the time Historically the data compilations were per-formed using pencil and paper and they have gradually developed into thepresent day computer operation that includes modern relational databaseand Web servers EXFOR compilation editors plot digitizers and opticalcharacter recognition technologies Since the beginning reaction data com-pilations were performed on a timely basis and archived in close cooperationwith the researchers Many scientists have contributed their original datasets to the EXFOR library Unfortunately this mode of operation has notalways worked perfectly and several important data sets were missed andthe NRDC network members are working on their recovery In addition theNRDC community has addressed the issues with the problematic and incor-rectly entered data compilations The database contents were reanalyzed andcorrected by the members of the Subgroup 30 of the Working Party on In-ternational Evaluation Co-operation of the NEA Nuclear Science Committee[5]

Data recovery (eg nuclear archeology) is one of the important functionsof the EXFOR operation Here the authors consider EXFOR entry 14329based on the PhD dissertation of JL Kammerdiener [6] University of Cal-ifornia Davis This thesis represents cost and time-expensive measurementswith unique target materials 239Pu 238U 235U Pb Nb Ni Al and C Thesethesis data were preserved as a paper copy only where results were shown asplots A new measurement with these targets would require lengthy delaycontingent on a program advisory committee approval process and may re-sult in a few million dollars of additional expenses Therefore this thesis andassociated graphic data were reanalyzed and digitized forty one years laterat the National Nuclear Data Center In this endeavor the EXFOR editor [7]and Java digitizer [8] developed in Sarov Russian Federation and SapporoJapan respectively were used The Fig 3 example illustrates the first 2 ofKammerdienerrsquos 171 thesis data records (subentries) The present compila-tion beginning subentry contains bibliographical and general information forall subentries such as 14 MeV incident neutrons energy in the common sec-tion while experimental data are compiled in the following subentries Thecompilation second subentry reaction field (13-AL-27(NEL)13-AL-27DA)indicates elastic neutron scattering differential data with respect to angle(DA) and the subentry status field (CURVE) reveals digitized data All ex-perimental data sets are placed within DATA and ENDDATA tags and theoriginal article units are preserved The well-structured compilation formatwas intentionally designed for further usage in computer systems It repre-sents a typical input file for the current Web and database system that willbe discussed in the following section

22 EXFOR Format

The EXFOR database format was introduced for data storage and in-formation exchanges between major data centers as a replacement of theSCISRS format [1] The present format is human-readable is 80 characterslong and includes opening and closing tags for all data and metadata setsEfforts to improve the EXFOR format are currently underway [9] and theseattempts will provide additional avenues for application developments Inthe present work the authors will adopt the EXFOR Basics publication [10]as an introductory guide to EXFOR format for advanced users the LEX-FOR manual is recommended [11] The EXFOR format is currently used forexperimental nuclear data archiving and dissemination and its file structureis shown in Fig 4 The experimental nuclear reaction data library consists of

COMMON DATA

Figure 4 Manifold structure of the EXFOR library Each database entry consists ofbibliographical and data subentries

data entries that contain complete records of individual experiments Eachexperiment may include multiple nuclear reaction data sets (subentries) andseveral research papers because EXFOR compilers group multiple publica-tions from a particular experiment into a single entry Another importantfeature of the library is that all experimental data are compiled as publishedonly obvious errors are corrected

Each entry is assigned a unique accession number each subentry is as-signed a subaccession number (the accession number plus a subentry num-ber) The subaccession numbers are associated with a data table throughoutthe life of the EXFOR system The subentries are further divided into thefollowing categories

bull Bibliographic descriptive and bookkeeping information (hereafter calledBIB information)

bull Common data that applies to all data throughout the entry or subentry

9

bull Data tables

In order to avoid repetition of information that is common to all subentrieswithin an entry or to all lines within a subentry information may be asso-ciated with an entire entry or with an entire subentry To accomplish thisthe first subentry of each work contains only information that applies to allother subentries Within each subentry the information common to all linesof the table precedes the table

EXFOR format was originally designed for data storage and interchangebetween the four data centers and it serves well for these purposes Howeverthe compilation format [12] may represent a problem for application devel-opers and other users who are not familiar with format specifics To over-come this obstacle a simplified computational format (C4) was introducedThe code X4TOC4 [13] converts EXFOR data sets to the easy-to-read datacolumns in C4 format The C4 format is used in the current system for dataplotting and further dissemination

23 EXFOR Database Dictionaries

Compilation databases often contain an extensive collection of dictionar-ies The EXFOR dictionaries list details for database keywords and codesand their identification numbers range between 1 and 999 [14] These dictio-naries are periodically updated with new keywords and codes and could besubdivided into three groups

bull The Archive dictionaries are the source of the contents of all forms ofthe dictionaries They contain all keys their expansions and additionalcodes as well as free text explanations for compilers

bull The DANIEL backup dictionaries contain all keys additional codesneeded for programs and most of the expansions These dictionariesare designed for interacting with computer programs

bull The EXFOR transmission dictionaries contain all keys (except for Dic-tionary 26 Unit families [14]) their expansions and free text expla-nations but not all additional codes needed for the checking and otherprograms

24 EXFOR Manual

EXFOR database its formats structures and relevant procedures areextensively described in the manual Historically it was maintained by theUS National Nuclear Data Center and recently it was transferred to theIAEA Nuclear Data section [10 11] The manual is absolutely essential forEXFOR database compilations and application developments

3 Platform-Independent Data Storage and Dissemination System

The development of nuclear reaction data storage and dissemination sys-tems has a very rich history There have been previous efforts to disseminatenuclear reaction data such as the Brookhaven Cross Section Information Stor-age and Retrieval System (CSISRS) that was introduced in 1971 based onthe VAX-VMS computer system This dissemination system was a revisedversion of the original SCISRS

The VMS platform became obsolete in the 90s due to the rapid progressof modern computing and introduction of World Wide Web technologies Inorder to improve the quality of nuclear data services and take advantageof the latest software and hardware developments the NNDC BNL andNDS IAEA started to work on a data migration project in 1999 followinga basic assessment of future options [15] This exploratory work culminatedat an International Workshop on Relational Database and Java Technolo-gies for Nuclear Data held at BNL September 11-15 2000 [16] As a re-sult of the workshop the two partners embarked on a project to migrateits databases to a UNIX-based relational database environment and signif-icantly upgrade Web Services employing the latest computer technologies[15 17] The migration project was successfully completed and the new nu-clear data Web service made available beginning in 2004 [18] General systemdesign and several distinct elements of the system such as Nuclear ScienceReferences (NSR httpwwwnndcbnlgovnsr) and Sigma Web Interface(httpwwwnndcbnlgovsigma) have been described previously [19 20] Atthe same time other popular features such as the very advanced and con-stantly evolving experimental nuclear reaction Web and data services werenever comprehensively described in the literature This publication is in-tended to fulfill this task and provide an extensive description of nuclearreaction data services

In the present work the authors describe the current status of the EXFORdatabase project which creates one of the foundations for the modern nuclear

11

data Web services The current system has been designed as multiuser andplatform independent environment [21] The cross platform capabilities havebeen achieved by extensive usage of Java technologies Java codes can bedeveloped on any device compiled into a standard bytecode and run on anydevice equipped with a Java virtual machine The current system includesJava Web servlets database connectivity and wrapper classes for a ZVViewplotting package [22] and legacy FORTRAN and C codes It is based oncommercially available software and hardware and contains many featuresof enterprise computer portals dealt with on a daily basis Two versions ofthe EXFOR database and Web retrieval systems are presently distributedserver and personal computer (portable) for multiple and individual clientsrespectively The server installation is briefly described in Ref [18] whilethe personal computer version is build on a standard compact disk thatis available from the IAEA upon request In subsequent subsections theauthors will describe hardware and software computer environments followedby software application developments careful analysis of Web features anda worldwide impact on nuclear data users

31 EXFOR Relational Database

The EXFOR database contains nuclear data sets for sim22000 experi-ments Rapid access to these data is of paramount importance for nuclearscience and technology professionals The first modern EXFOR Web dis-semination and data storage system was developed at the NDS IAEA incooperation with the NNDC BNL [21] It is a multi-platform product thatwas developed for the nuclear data services migration project to a TomcatWeb and SybaseMySQL database servers environment [18] Later the nu-clear databases were transferred from Sybase to MySQL servers The mod-ern relational database servers allow access to data using Structured QueryLanguage (SQL) The SQL language is easy to learn and use it allowingmanagement of the databases and building Web interfaces for data searchesmanagement and updates The underlying software converts these requestsinto corresponding SQL statements that are passed to the database to harvestdatabase outputs

MySQL server is a robust database system that can be operated on mul-tiple computer platforms using community or enterprise licenses Initiallythe NDS IAEA service was based on MySQL while the NNDC operatedenterprise Sybase servers and later transferred to MySQL enterprise serversIn recent years both centers migrated to MySQL community edition servers

12

The EXFOR database has been successfully integrated with the Evalu-ated Nuclear Data File (ENDF) libraries [23 24 25 26 27 28 29] bibli-ographical Computer Index of Nuclear (reaction) DAta (CINDA) [30 31]and Nuclear Science References databases [19] Its contents are also used inSigma Web Interface [20] some of its components are used in JANIS (JAva-based Nuclear data Information System independently developed by the NEADatabank) [32] The EXFOR relational database project has evolved andmatured substantially in the last fifteen years compared to its initial version[21 18] and an extensive description of its latest features is presented below

311 EXFOR Database Schema

The schema describes a database structure in a formal language supportedby the database management system In a relational database the schemadefines the tables fields relationships views indexes procedures and otherelements

The simplified version of EXFOR relational database schema is shown inFig 5 The EXFOR schema includes tables that contain data metadataand dictionaries such as X4SRC ENTRIES and AUTHORS respectively Itincludes relationships between data tables eg ENTRY and SUBENT metadata tables are linked using an EntryID relationship The current databaseschema provides a glimpse into the present system storage of experimentalnuclear reaction data sets

312 Database System Operation

The EXFOR operation includes contributions from the data groups affil-iated with the network of Nuclear Reaction Data Centres (NRDC) [33] andNon-EXFOR data sources The NRDC supplies the database with new andrevised data compilations dictionaries and manual updates Bibliographicalmetadata original publication PDF files and data renormalization informa-tion are provided through separate channels All of these nuclear science andbibliographical data are processed and stored in a relational database thatincorporates text compilation and articledocument PDF files for the major-ity of EXFOR entries Due to major publishersrsquo subscription rules the PDFfiles are not available for external users The Java-based computer programsprocess contributions and fetch data retrievals as EXFOR-formatted filesZVView plots PDF files and many other custom formats for remote Weband local users The EXFOR database operation workflow diagram is shownin Fig 6

32 EXFOR Web Interface

Since introduction of the World Wide Web it is essential for data and re-search centers to provide direct access to nuclear databases [18 34 35 36 37]The EXFOR Web retrieval interface is an integral part of both IAEA andNNDC Web Services [18 34] To provide more robust scalable architecturesatisfy cyber security requirements and protect nuclear data services from asingle-point failure the Web and database servers are physically separatedThe Web server has the ApacheTomcat [38 39] Web production environ-ment installed All servers are running the Linux (Red Hat SUSE etc)operating system The initial version of the present interface became opera-tional fifteen years ago and eventually grew to its current state The interfaceis based on current computer technologies and provides retrieval of databasecontent in HTML Text BibTex and PDF formats It also produces special-ized outputs in C4C5 Application Programing Interface (API)XML andR33 for nuclear model codes application developers and Ion Beam AnalysisNuclear Data Library (IBANDL) [40] users community respectively

Data plotting is performed using the ZVView software package that hasbeen written in C and designed for evaluators of nuclear reaction data toperform efficient interactive analyses of cross section data retrieved from thenuclear data libraries [22] The main function of ZVView is to plot these data

15

for comparison using a variety of options to study graphical numerical andbibliographic information along with the possibility of analyzing the resultsof the userrsquos evaluations Since 2010 the ZVView program has been extendedto plot 2-dimensional arrays Z(XY) with the main purpose of displaying cor-relation matrices The package allows users to change plotting parameterssuch as type of data view (curve histogram map 3D animation symbolsof points colors error bars) logarithmic and linear scales zoom split plotto sub-windows smoothing by least-squares method choice of data and au-thors to be plotted scans of their points and changing language on the flyThe Web-ZVView program implements the majority of these functions asintegrated part of EXFOR and ENDF Web retrieval systems

The current Web interface is a very sophisticated product that reflectsthe overall complexity of nuclear reaction data The immense variety andvolume of the archived quantities require advanced data retrieval capabilitiesat the same time a large number of EXFOR users are still looking for simpleretrievals of reaction cross sections To accommodate these different usergroups four levels of EXFOR retrievals have been introduced basic (simple)extended keywords and expert

321 Simple EXFOR retrievals

The majority of EXFOR users are not familiar with the databasersquos ad-vanced structure or its philosophy This user group includes nuclear scien-tists engineers and graduate students that need direct access to the latestnuclear reaction data sets To satisfy their needs the authors have developedsimple EXFOR retrievals that are based on target reaction experimentalquantity product energy range authors publication year and accessionnumber search parameters All search fields are based on a logical ldquoORrdquooperator () that returns the Boolean value true if either of the operandsis true and returns false otherwise Therefore empty fields are ignored by adata search query and users can easily construct database queries using Webinterface search fields To demonstrate the present Web interface graphic anddata capabilities the authors will consider a case of 235U(nf) reaction crosssections Fig 7 shows a simple retrieval for the following input parameterstarget = 235U reaction = nf and quantity = cs

To improve user experience a simple text string Google-like search hasbeen recently added to the EXFOR Web interface It is located on the topright side of the EXFOR front page This search is intended for less sophis-ticated EXFOR users who prefer to mine experimental data using common

nuclear physics concepts The EXFOR interface also contains online helpdisplayed as question mark buttons on the right side of the search boxesThese buttons produce pop-up windows that have information on text boxinput parameters and provide access to EXFOR dictionaries

322 Advanced EXFOR retrievals

EXFOR is the only nuclear physics database that stores extensive de-scriptions of experimental results and facilities In fact these data representa treasure trove for investigation of research trends in nuclear physics [3] andprovide complementary background for nuclear data evaluations These datacan be extracted using extended keywords and expert requests

The extended retrieval provides additional capabilities for creating sophis-ticated database queries that include bibliographical metadata geographicalorigin (area country institute) NSR keynumbers (NSR database analoguesof EXFOR accession numbers) and compilation timing information

Keyword retrieval allows queries for experimental quantities that cannotbe easily found anywhere else detector method monitor facility incomingsource and spectrum data analysis detected particles and radiations and

experimental data originsThe expert retrieval supplies capabilities for searching for outgoing parti-

cle parameters data units ranges for experimental data points and EXFORcompilation centers individual compilers and data transmissions As it wasmentioned previously all text box search fields are implemented as a logicalldquoORrdquo operator and therefore missing search fields are ignored by SQL dataqueries

33 EXFOR Examples of Requests and Video Guides

The EXFOR system has matured over the years into a very advancedproduct and several complex features represent a challenge for new users Toovercome these issues the webpage News display box numerical and plottingexamples of requests and video guides (httpswww-ndsiaeaorgexforx4guide)have been prepared These resources provide constant updates on new EX-FOR system features and share best user practices The EXFOR examplesare intended for user education purposes and supply additional insights on in-terface capabilities The broad scope of examples helped to improve EXFORuser experiences and such policies contributed to the worldwide popularityof the service

34 Worldwide Impact of EXFOR Web Interface

The EXFOR interface is a gateway to the latest experimental nuclearreaction data stored at the IAEA and NNDC databases and it has a verybroad spectrum of usage worldwide In order to provide the best qualityof services the authors monitor the interface operation [18 41] Monitor-ing includes collection of web statistics geographical coverage network dataanalysis and estimates of database usage The EXFOR database retrievalstatistics are very conservative and completely based on a count of success-ful database retrievals any Web browser hits are ignored Retrievals fornon-existing entities in the database (eg author reaction target) whichproduce an empty output file are rejected Complete information for eachretrieval is recorded in separate Web statistic data files and usually sim300retrievalsday are observed from the IAEA and NNDC websites

The absolute number of Web retrievals provides only a partial estimateof product usage To further estimate the impact of the current productretrieval statistics can be complimented with the Google Scholar data TheScholar Web application allows retrieval of information on the EXFOR Webapplication usage from research articles A simple Google Scholar search for

4 Related Nuclear Reaction Data Projects

The EXFOR computer database is an integral part of nuclear data Webservices is firmly related to nuclear reaction data evaluations and requiresaccess to nuclear bibliography The combined development of the experi-mental evaluated and bibliographical nuclear reaction databases was a costeffective solution that allowed reuse of Java classes Web implementation of

plotting packages and reduction of overall time for application developmentand testing

41 ENDF

ENDF is a core nuclear reaction database containing evaluated (recom-mended) cross sections spectra angular distributions fission product yieldsthermal neutron scattering and photo-atomic and other data with an em-phasis on neutron-induced reactions ENDF library evaluations are basedon theoretical calculations normalized to experimental data with an excep-tion of neutron resonance region where priority is given to experimentaldata ENDF evaluations consist of complete neutron reaction data setsfor particular isotope or element (ENDF material) They cover all neu-tron reaction channels within the 10minus5 eV - 20 MeV energy range Nowa-days in many evaluated data libraries this energy range is extended tohigher energies All these data sets are stored in the internationally-adoptedENDF-6 format that is maintained by the Cross Section Evaluation Work-ing Group (CSEWG) and publicly available at the NNDC and NDS web-sites httpwwwnndcbnlgovendf and httpwww-ndsiaeaorgendf re-spectively Cross section evaluations are of great importance for nuclearenergy and science applications and they are performed internationally forENDF JEFF TENDL JENDL ROSFOND and CENDL libraries [24 2526 27 28 29] in the USA Europe Japan Russian Federation and Chinarespectively

The EXFOR project is a primary source of experimental nuclear reac-tion data for neutron cross section evaluations In practice many ENDFevaluations are produced using nuclear reaction model codes EMPIRE orTALYS [42 43] that contain EXFOR database connectivity modules Thecomputer codes are used for calculation neutron-induced reaction theoreticalcurves data analysis and comparison with experimental data These eval-uations are critically important for many applications because they provideevaluated neutron cross sections for operation of nuclear power plants andGEANT and MCNP computer codes [44 45]

The ENDF Web interface takes its contents from a separate ENDF re-lational database It contains the most complete international collection ofevaluated nuclear reaction libraries includes data analysis capabilities andintegrated with experimental data The interface shown in Fig 10 servesevaluated data in many output formats and incorporates the ZVView pro-gram [22] The IAEA and NNDC interfaces are slightly different on a client

42 CINDA

Nuclear bibliography is essential for nuclear reaction data compilationsCINDA contains many historic publications that are not available in anyother database These publications are grouped by experiment and thedatabase allows application of energy range criteria for data searches Theseunique capabilities are still in demand by nuclear data evaluators Currently

separate CINDA data compilations are terminated and CINDA contents areextended by new information from the EXFOR and NSR databases

CINDA contains the most extensive nuclear reaction bibliography it isintegrated with the EXFOR Web retrieval system and allows users to searchfor information that is not available in EXFOR The database interface in-cludes all major EXFOR search fields and provides data outputs in text andHTML formats For example to retrieve nuclear bibliography for 235U(nf)reaction cross sections the following input parameters are assumed target= 235U reaction = nf and quantity = cs As shown in Fig 11 CINDAdatabase output consists of 2406 publications and 2736 reactions

5 New Features of EXFOR Web Interface

Originally EXFOR Web Interface was created to perform only basic op-erations data search retrieval and presentation It is now part of a largeand developed Web System including extended functionality and tools forregular [external or traditional] users EXFOR compilers and ENDF andENSDF [47] evaluators There are many interesting EXFOR Web interface

23

features that have been developed in recent years and readers may explorethem using the News display box information and the search textbox linksdisplayed above The next section will concentrate on experimental dataprocessing renormalization covariance matrix and inverse reaction crosssection calculations

51 User Data Uploads

EXFOR library compilations are conducted by the NRDC compilers incooperation with researchers The compilers often interact with the scientistsin order to obtain original data and complementary details they are requiredto discuss EXFOR compilations before submitting them to the database Onthe other hand scientists often need to compare their latest findings with theexisting data sets Consequently a direct link between research and compila-tion activities is necessary It can be accomplished with a simple Email inter-action using the httpwwwnndcbnlgovexforx4submithtm webpage forguidance or using a sophisticated Web tool interface httpswww-ndsiaeaorgexforx4datahtmThe Web tool system does not require a password however users have toauthenticate themselves with an ldquoIrsquom not a robotrdquo test On the followingpage scientists can provide author reaction method information and datadescription and copy and paste their data in x y δy or user-specified for-mats into the corresponding text box Upon completion of this operationdata and associated metadata are converted to EXFOR format and sent toEXFOR Web retrieval system for data operations such as plotting calcu-lations and comparisons with existing data from the EXFOR and ENDFdatabases Users can process their data by utilizing Web tools for construct-ing covariance matrices or inverse reaction cross section calculations Theinterface also can be used for new data submissions to the NRDC networkfor further analysis and compilation

The complementary general purpose myPlot package provides additionalavenues for uploading and displaying Web interface usersrsquo data This Web-ZVView program extension is available under httpswww-ndsiaeaorgexformyplothtm

nuclear physics processes and limitations of experimental techniques Be-sides many results in the past were produced relative to presently-outdatednuclear standards (monitor measurements) these standards have improvedover time and data reanalysis and corrections are urgently needed

The EXFOR interface addresses these issues with a set of options au-tomatic data renormalization to new monitor data [48] or user and expertrecommended corrections [49] The automatic renormalization is availablefor EXFOR compilations that include information on monitor reaction dataAn example of automatic EXFOR data renormalization is shown in Fig 12Here the 25-MN-55(nα)23-V-52 reaction data and their uncertainties [50]were renormalized using the latest monitor data [51 49] with energy depen-dent correction factor varying from 1016 to 1125 Additional details onthis subject can be obtained from the EXFOR examples and video guide(httpwwwnndcbnlgovexforx4guidex4renorm2indexhtm)

53 Covariance Matrix Calculation using Experimental Uncertainties

During the last few years there is a growing interest in covariance dataamong the nuclear physics community The experimental nuclear data co-variances are needed by data evaluators nuclear model code developers andexperimentalists The EXFOR database contains a limited number of co-

25

Result of the reconstruction of the full matrix (Fig3 Appendix-5) is different from reported by the authors only in one point (Total reconstructed uncertainties are systematically lower then authorsrsquo values probably because of different rounding ndash this needs further checking)

Concluding remarks

The Web tool has two parts translation of EXFOR files to C5 and interactive construction of a correlation matrix

The first part allows construction of a rough estimation of the covariance matrix on the basis of statistical and systematic uncertainties without any assumptions and it can be directly used by some program packages Although this part does not use additional knowledge about specific partial uncertainties it leads to significant progress in covariance data

The second (interactive) part of the tool relies on the experience of evaluators and their assumptions about correlations This part is intuitive and therefore subjective It can help in individual evaluations but probably not as a routine part in large packages

Such a tool may be the only practical way to construct covariance matrices for old data stored in the EXFOR database

Discussion Practicing with such a tool can improve understanding and formulation of recipes for constructing covariance matrices based on providing partial errors and correlation components for different cases It can also help in the development of the EXFOR format via formalization of parameters from these recipes

After comprehensive testing and discussion in the nuclear data community it can be recommended to experimentalists for calculation of the final correlation matrices from partial uncertainties [10] and supply the recipe for reconstruction of the matrices to the EXFOR compilers to store them in the EXFOR database

54 Inverse Reaction Calculation

The EXFOR Web interface collection of data evaluation tools has beenrecently complimented with an inverse reaction calculator which is basedon the nuclear reaction reciprocity theorem [54 55] It allows extracting areaction cross section if an inverse reaction is known For 1 + 2 rarr 3 + 4and 3 + 4 rarr 1 + 2 processes the cross section ratio is

σ34σ12

=m3m4E34(2J3 + 1)(2J4 + 1)(1 + δ12)

m1m2E12(2J1 + 1)(2J1 + 1)(1 + δ34) (1)

where E12 E34 are kinetic energies in the cm system J is angular momen-tum and δ12=δ34=0

As an example of application of nuclear astrophysics reaction data forcalculations of reactor data one of the major neutron sources for s-processnucleosynthesis is 13C + α rarr16 O + n reaction and its inverse reaction isone of the major nuclear reactor neutron poisons The alpha-induced re-actions have been extensively studied due to general availability of heliumbeams while the inverse neutron reaction measurements are more challeng-ing Therefore it is wise to use the well-known alpha-induced reaction oncarbon for the oxygen neutron capture cross section estimates Using the re-cent measurement of 13C+α reaction by S Harissopulos et al [56] for inversereaction cross section calculations the corresponding Web interface inputsare target = 13C reaction = an quantity = cs and product = 16O On thenext screen the example use the S Harissopulos et al data set marking

1 Introduction

Since the dawn of the nuclear age access to the most recent nuclear dataplayed a crucial role in nuclear physics research and application develop-ment These data were originally disseminated as paper copies for designatedusers and eventually evolved into the present-day computer files distributedover the World Wide Web The National Nuclear Data Center (NNDC)Brookhaven National Laboratory (BNL) and Nuclear Data Section (NDS)International Atomic Energy Agency (IAEA) have always been pioneers innuclear data collection evaluation and dissemination They have been pro-viding remote electronic access to their databases and other information since1986 In this work the authors will concentrate on the present state of storageanalysis and worldwide distribution of low- and intermediate-energy nuclearreaction data

EXFOR experimental nuclear reaction database [1 2] is the worldrsquos primerepository for reaction data compilations The EXFOR library was estab-lished in 1967 at a meeting of the four major nuclear data centers BrookhavenNational Laboratory Upton NY (Area 1 USA Canada) Nuclear EnergyAgency (NEA) Databank Paris France (Area 2 Western Europe andJapan) International Atomic Energy Agency Vienna Austria (Area 3Asia Eastern Europe Latin America Africa Australia and Oceania) andInstitute of Physics and Power Engineering (IPPE) Obninsk USSR (Area4 Soviet Union) [1] This project was based on previously-existing ef-forts such as the NNDC predecessorrsquos Sigma Center Information Storageand Retrieval System (SCISRS) and the associated format Currently theEXFOR project is an international collaboration under the auspices of theInternational Atomic Energy Agency and 13 nuclear data centers from theUSA OECDData Bank (France) IAEANDS (Austria) Russian Federa-tion China Hungary India Japan Kazakhstan Korea and Ukraine regu-larly contribute to it

2 EXFOR Database

The exchange format library was created in support of nuclear energyfundamental research and application development activities The initialdatabase scope was limited to neutron-induced reaction quantities Later thescope was extended to charged-particle and photon-induced reactions withenergies below the pion production threshold Presently neutron- proton-
