Overview of JENDL High-energy FileOverview of JENDL High-energy File
Neutron- and proton-induced data up to 3 GeV
It contains data for 106 nuclei in latest version (2007)
It includes cross sections such as total, elastic scattering,DDX of emitted light-particles ( n, p, d, t, 3He, ),gamma-ray spectra, Prod. of residual nuclei
JENDL-3.3 is adopted below 20 MeV for neutron data

SummarySummary
Overview of JENDL/HE-2007 is presented in this talk
Some differences are seen among the evaluations
JENDL-4 project is now on going, and it will be releasedin the end of FY2009.
Iwamoto-Harada coalesce model was partially adopted for composite particle production cross sections.
