JENDL/HE-2007 & On going Activities for JENDL-4 S. Kunieda Japan Atomic Energy Agency Y. Watanabe Kyushu University IAEA 1-st RCM of CRP on FENDL-3.0, 2-5 Dec. 2008
Overview of JENDL High-energy File Neutron- and proton-induced data up to 3 GeV It contains data for 106 nuclei in latest version (2007) JENDL-3.3 is adopted below 20 MeV for neutron data It includes cross sections such as total, elastic scattering, DDX of emitted light-particles ( n, p, d, t, 3He, a ), gamma-ray spectra, Prod. of residual nuclei
List of Nuclei Released as JENDL/HE-2004 ( 66 nuclei ) Released as JENDL/HE-2007 ( 66+40=106 nuclei ) Evaluation is not accomplished yet … It will be released as a supplement in next year
