Nuclear data evaluation for JENDL high energy file and its benchmark

An overview is reported of nuclear data evaluation for the JENDL High Energy (JENDL-HE) file which contains neutron and proton cross sections for energies up to 3 GeV for the whole 132 nuclides. The JENDL-HE evaluations are performed on the basis of experimental data and theoretical model calculations. For the cross section calculations, a hybrid calculation code system is constructed using some available nuclear model codes and systematics-based codes. The evaluated cross sections are compared with available experimental data and the other evaluations. Some preliminary results of benchmark tests are also presented. (author)
