2200 m / s NEUTRON ACTIVATION CROSS-SECTIONS

R. SHER Stanford University, Stanford, Cal i f . , United States of America

ABSTRACT. 2200 m / s neutron activation cross-sections for a large number of isotopes of interest to neutron activation analysis are presented. In addition to the cross-sections, values are given for the half-lives of the activities formed and the cross-sections for activation of isomeric and ground-states, if these are both of interest.

ABSTRACT. A compilation is given of infinite-dilution resonance integrals (1/v contribution included). Most results have been obtained from experiments, although in some cases evaluated data have also been included. The resonance-integral values have been normalized to conform to various standards, mainly those from 197 Au and 59 Co.

ABSTRACT. The tables of recommended cross-sections are intended mainly to be of practical use in activation analysis and also in nuclear chemica l research or systematic nuclear physical analysis. Therefore the compilat ion is not extended to the reaction types (n, d), (n, y), (n, T) and (n, t), which are usually of minor practical interest. The literature before 1 March 1972 has been considered. The recommended values were deduced from the data by preferentially using series of newer publications. The mean values are characterized by typical errors; it was not possible to calculate weighted mean values because the information given in the literature is sometimes too incomplete to be treated consistently. Occasionally the well-known semiempirical formulae were applied. In some cases no recommendation could be given because of lack of a sufficient number of reliable measurements. The interval of the excitation functions is divided into three groups: 13. 9 - 14 .29 MeV, 14. 3 - 1 4 . 6 9 MeV and 14 .7 - 15. 09 MeV neutron energy. Usually one recommended value for each interval is given. Special attention should be paid to the original literature because in several cases the main sources of errors are the use of different standard values of cross-sections and the incomplete knowledge of the decay scheme of the radioactive isotope considered.

Part 2

GRAPHS OF EXCITATION FUNCTIONS

(Range: 1 - 37 MeV)

ABSTRACT. The compi la t ion is restricted to exci tat ion functions that can be measured by act ivat ion techniques. For pract ical purposes, mainly absolute cross-sections are needed; therefore, exci ta t ion functions given only in re la t ive units were excluded. As the exci tat ion functions given in the l i terature frequently differ for several reasons, less in shape but more in the absolute cross-section values, we desisted from deducing mean exci tat ion functions by averaging over the published data . Where there are significant differences in the absolute values, the exci tat ion functions should be renormalized by using the 14-MeV cross-section values given in Part 1.

INTRODUCTION

The l a s t s u r v e y on exc i ta t ion func t ions of neu t ron - induced r e a c t i o n s was publ i shed in 1965 [1], In the m e a n t i m e , a c o n s i d e r a b l e n u m b e r of p r e c i s e m e a s u r e m e n t s on t h e s e t o p i c s ha s been p e r f o r m e d , m a i n l y with neu t rons of the 12- to 20-MeV reg ion .

The fol lowing compi la t ion i s r e s t r i c t e d to exc i ta t ion func t ions tha t can be m e a s u r e d with ac t iva t ion t echn iques . In p a r t i c u l a r , the exc i ta t ion func t ions of r e a c t i o n t r a n s i t i o n s lead ing to s i n g l e - e n e r g y s t a t e s of the r e s i d u a l nuc leus — e . g . (n, o0), (n, »j) t r a n s i t i o n s — a r e excluded f r o m th i s compi la t ion .

A s to the in tent ion of th is compi la t ion , the u s e r i s r e f e r r e d to the i n t r o d u c t o r y c o m m e n t s of P a r t 1. The s a m e app l i e s to the n o m e n c l a t u r e of the r e a c t i o n types and a b b r e v i a t i o n symbo l s . In c o n t r a s t to the p r o c e d u r e u s e d in the t a b l e s to d e r i v e the se t of r e c o m m e n d e d c r o s s - s e c t i o n va lues f o r neu t ron e n e r g i e s of about 14 MeV, we did not want to deduce m e a n exc i ta t ion func t ions by a v e r a g i n g o v e r o r ca lcu la t ing f r o m the publ ished data .

The to ta l i ty of the exc i ta t ion func t ions p r e s e n t e d h e r e i s to be u n d e r -stood a s a c r i t i c a l compi la t ion that ha s been worked out in the fol lowing way. S ta r t ing f r o m s o m e o lde r compi l a t ions (Refs [1-3]) and u s i n g the CINDA R e p o r t [4], a l l ava i l ab le publ i shed exc i ta t ion func t ions w e r e ga the red t o g e t h e r . Of ten the exc i ta t ion func t ions a r e publ ished in g raph ic f o r m only; t h e r e f o r e , the g r a p h s given h e r e m a y contain s m a l l e r r o r s which a r i s e when e s t i m a t i n g the v a l u e s f r o m the o r ig ina l g r a p h s .

F r o m th i s s tock , f i r s t a l l those exc i ta t ion func t ions w e r e excluded that w e r e given in r e l a t i v e un i t s only. T h i s c o n c e r n s m a i n l y the p a p e r s of P r e s t w o o d and B a y h u r s t [5] and F e r g u s o n and Albe rgo t t i [6], Second, t h o s e exc i ta t ion func t ions w e r e omi t ted tha t showed s t r o n g and unexpla inab le dev ia t ions f r o m the m a j o r i t y of the o the r m e a s u r e m e n t s f o r the s a m e r e a c t i o n o r tha t w e r e in c o n t r a s t to r e l i a b l e t h e o r e t i c a l ca l cu la t ions o r p r e d i c t i o n s ( this app l i e s m a i n l y to s o m e (n, 2n) exc i ta t ion func t ions c o m p a r e d with s t a t i s t i c a l m o d e l ca lcu la t ions ) .

CROSS-SECTIONS F O R FISSION NEUTRON S P E C T R U M INDUCED REACTIONS

A. CALAMAND Nuclear Data Section, International Atomic Energy Agency, Vienna, Austria

ABSTRACT. A review is given of cross-sections averaged in a uranium-235 fission neutron spectrum. The review extends to all integral measurements available in the literature up to April 1973 for (n, p) , (n, a ) , (n, 2n) and ( n , n ' ) reactions. Whenever possible, the cross-sections have been renormalized to a standard value of 1250 ± 70 mb for the uranium-235 fission cross-section averaged in the thermal fission neutron spectrum of uranium-235. Recommended values have been attributed. Furthermore, averaged (n, p) , (n , a ) and (n, 2n) cross-sections have been estimated for all stable and a few long-lived isotopes and are compiled in a separate table.

(1) The fission flux was determined by comparison with another fission flux produced in a simpler geometry

such as a converter . Hughes' old data set could not be ignored since some of his measurements are still unique

or among the few. It was then necessary to perform an empi r i ca l renormal iza t ion . This was done by comparing

Hughes' values with well established ones whenever possible. Hughes' data were found to be consistently too

low by an average factor of 1 . 6 .

(2) The fission flux was deduced from the power generated in the uranium rod. This power was calculated

from the flow and temperature rise of the cooling water . No renormal iza t ion was performed.

(3) Bresesti 's da ta were first reported re la t ive to a va lue of 0 . 6 1 mb for Z 7Al(n, a ) 2 4 N a (Ref. BR67). After

comparison with da ta obtained by integration of exci ta t ion functions over various spectral representations for the

fission spectrum, these da ta were rescaled by a factor of 1 . 1 4 . The values for 4 6 T i ( n , p ) 4 6 S c , 5 8 Ni(n , p ) 5 8 m C o

and s z Mo(n , p) ®2Nb which do not appear in Ref. BR70 were mult ipl ied by 1 .14 by Fabry (Ref. FA72) and included

in his eva lua t ion .

(4) The fast neutron flux was monitored using the following standards: 104 mb, 1 .4 mb and 0 . 6 3 mb for

^ N i f n . p ^ C o , " M g ( n , p ) 2 4 N a and z , A l ( n , oc)24Na, respect ively. New values for these standards (see Tab le I)

lead to an average renormal izat ion factor of 1 . 1 1 .

(5) The fission spectrum averaged cross-sections ö were found by correcting the average cross-sections o 0

measured in a c r i t i ca l assembly of enriched uranium. In this case, our renormalized values were obtained by

mult iplying Nasyrov 's data by Fabry ' s rescaling factor, which is 1 .175 for these da ta .

(6) The core cent re react ion ra te measurements of McElroy have been transformed by Fabry (see Ref.FA72)

into fission spectrum averaged cross-sections. Fabry ' s scaling is re la t ive to a value of 0 .73 i 0 .015 for the 2 7 Al(n, a.) cross-section.

(7) Fabry 's data were directly quoted from Ref.FA72, although pract ical ly all of them were reported in

Ref. FA70/1. Although they result from absolute measurements, using the technique described in Ref. FA67

(see Note (9) for description of a similar technique), they are all consistently scaled to the uranium-235 average

fission cross-section value of 1335 mb, which can therefore rightly be considered as the standard.

(8) The double rat io measurements of Gründl (Refs GR67, GR68) have been converted to fission spectrum

averaged cross-sections by Fabry. All detai ls can be found in Ref. FA72.

306 CAL AM AND

(9) Depuydt et al . (Ref. DE62) have used the converter technique for their measurements. The absolute value of the fast flux <£f was determined from the absolute value of the thermal flux $ t j j by means of the relation :

= « £ f * t h G f C O I

where v = 2.43 ± 0. 02 is the mean number of neutrons emitted per thermal fission of uranium-235

If = 23 .8 ± 0 . 2 cm"1 is the macroscopic fission cross-section of the converter, computed for a microscopic thermal fission cross-section of (587 ± 6) b for uranium-235

G is a geometrical factor

fcor takes into account the secondary processes in the facility

<tth is determined using (98.8 ± 0 .3 ) b for the thermal capture cross-section of gold-197

We have not renormalized in this case.

(10) The data are based on the assumption that the fission-neutron flux inside the uranium receptacle slug

equals the thermal neutron flux outside the slug; they were renormalized by multiplying by 69 /22 .5 as shown

by Mellish (see Ref. ME60).

(11) Two standards were used for the neutron flux determination.- 0.54 mb and 10.6 mb for 6 3 Cu(n ,a ) and 4 6 Ti (n , p) cross-sections, respectively.

( 12) Neutron multiplication was measured in beryllium spheres. The quantity 5 n 2n " °n a w a s determined and s n 2 n was deduced taking 10 mb for the 9 B e ( n , a ) cross-section. No renormalization.

(13) The same method as in Note (12) was used with the same value of 10 mb for the ®Be(n,a) cross-section. No renormalization.

(14) Three standards were used for the neutron flux determination: 95 ± 6 mb, 61 ± 8 mb and 9. 8 ± 1 .1 mb for the ^ N i t n . p ) , a F e ( n , p ) and 4 6 T i ( n , p ) cross-sections, respectively.

(15) Green has used a manganese sulphate bath technique to make an accurate measurement of the ®Be(n, 2n) cross-section averaged over a pure ZKCf fission neutron spectrum. The technique measures neutron multiplication and therefore eliminates completely the need for a flux measurement. The 9Be(n, a) reaction was corrected using a calculated average cross-section of 38.2 ± 3 . 8 mb. Fission neutron spectra of 2MCf and Ö 5U are similar enough to justify averaging (n, 2n) cross-section values of Green and of Felber.

(16) The original value of 65 mb has been corrected by Fabry (see Ref. FA72).

(17) Data communicated by S. B. Wright to W.H. Martin and D.M. Clare.

(18) The original value was computed by integration of an evaluated excitation function o(E) over a Watt spectrum. It is clearly our recommended value in this case. Whenever a check is possible, the agreement between our recommended values and Barrall's computed values is generally good, therefore we can arbitrarily use a 1 0 r e l a t i v e error.

(19) Nasyrov's computed values are based on the relation 00 oo

3 = ° e f f ¡ X iE) dE ( / X(E) dE = 1) where X(E) ~ e"°-7 6 6 E

Eeff 0

The calculation was performed whenever it was possible to choose o e f f among experimental or evaluated data. When no other data are available, Nasyrov's calculated data become our recommended values with an arbitrary relative error of 30%.

(20) Two standards were used for the neutron flux determination: 72.6 mb and 0.307 mb fór ^Fe tn , p) and , 5 As(n , 2n) cross-sections, respectively.

(21) Four standards were used for the neutron flux determination: 92 mb, 3 .4 mb, 1 .2 mb and 0.63 mb for 5 8 N i ( n , p ) , 2 7 Al(n ,p ) , 2 4 Mg(n ,p ) and z , Al(n, OÍ) cross-sections, respectively.

(22) The standard chosen depends too much upon the shape of the fission spectrum to allow a renormalization.

(23) Ricabarra et al . have measured the following ratio:

5 [ 3 1 P(n, p ) a S i ] / 5 [ 3 z S(n,p) 3 2 P] = 0 . 5 1 i 0 .03.


(24) Value calculated from an empi r i ca l formula valid ta 8 < Z s 42. This value becomes our recommended

value for which we est imate a 30% rela t ive error.

(25) Cross-section averàged over a reactor spectrum from 0 . 1 MeV to infini ty. The standard reaction used was 2 1 Si(n, p) , for which an average cross-section of ( 10 .4 ± 2 . 4 ) mb, computed over the same energy range, has

(26) Hegediis has measured the excitat ion function of 9 3 Nb(n, n ' ) 9 3 m N b which he integrated over a Watt

spectrum (Ref. WT52) to obtain 97 ± 35 mb . He used a standard value of 595 ± 150 mb for I 0 3Rh(n, n , ) 1 0 3 m R h .

This va lue was computed from Butler 's exci tat ion curve (Ref. BT68) using a larger conversion coeff ic ient ratio

a k / a for 1 0 3 mRh ( 0 . 1 3 1 instead of 0. 099) . This explains the lower value of 595 mb instead of 716 mb obtained

by Butler and Santry. The error on the 9 3 N b ( n , n ' ) 9 3 m N b cross-section includes the uncertainty of the standard.

(27) Obtained by integration of a Vogt and Cross (Ref. VC64) exci ta t ion function over a Cranberg spectrum

(Ref.CR56). No renormal iza t ion .

(28) The measured exci tat ion function was integrated over a Cranberg spectrum (Ref. CR56). Value not

retained for the average (see Note (26)) . No renormal izat ion.

(29) Kimura e t a l . measured the exci tat ion curve up to 4 . 6 MeV. Above this value, they used the curve

calculated by Vogt and Cross (Ref. VC64) to compute 5 using a Cranberg spectrum (Ref.CR56).

EXCITATION FUNCTIONS FOR CHARGED-PARTICLE-INDUCED NUCLEAR REACTIONS IN LIGHT ELEMENTS AT LOW PROJECTILE ENERGIES

J. LORENZEN, D. BRUNE Aktiebolaget Atomenergi, Studsvik, Sweden

ABSTRACT. This compilation of data should be useful in various fields of nuclear applications, with the emphasis on charged particle activation analysis. Activation analysis of light elements using charged particles has proved to be an important tool in solving various problems in analytical chemistry, e . g . those associated with metal surfaces. Scientists desiring to evaluate the distribution of light elements on the surface of various matrices using charged-particle reactions require accurate data on cross-sections in the MeV-region. Also, a knowledge of cross-section data and yield functions is of great interest in many applied investigations involving work with charged particles, such as radiological protection and health physics, material research, semiconductor material investigations and corrosion chemistry. The authors therefore decided to collect a limited number of data which find use in these fields. Although the compilation is far from being complete, it is expected to be of assistance in devising measurements of charged-particle reactions in Van de Graaff or other low-energy accelerators.
