Evaluation of Cross Sections of ~(56)Fe up to 3 GeV and Integral Benchmark Calculation for Thick Target Yield

摘要

The neutron and proton cross sections of ~(56)Fe were evaluated up to 3 GeV. JENDL High Energy File of ~(56)Fe were developed for use in transport calculation. For neutrons, the high-energy data are merged with JENDL3.3-file. Integral benchmark calculations for thick target neutron yields (TTY) for 113 MeV and 256 MeV proton bombardment of Fe targets were performed using the evaluated libraries. Calculated TTY neutron spectra were compared with experimental data. For 113 MeV, calculated TTY at 7.5 degree underestimated in the emitted neutron energy range above 10 MeV. For 256 MeV, calculated TTY well agree with experimental data except below 10 MeV.
