摘要：
Neutron nuclear data on Br-79.81 and Kr-78,Kr-80,Kr-82,Kr-83,Kr-84,Kr-85,Kr-86 have been evaluated for the evaluated nuclear data library JENDL-4.0 in the energy region from 10(-5) eV to 20 MeV. The resolved resonance parameters were adjusted so as to reproduce recommended or measured thermal capture cross sections for some isotopes. The statistical model was applied to calculate the cross sections above the resolved resonance region. In the calculations, coupled-channel optical model parameters were used for neutrons. Preequilibrium and direct-reaction processes were taken into account in addition to the compound process. The present evaluation is consistent with available experimental data. The evaluated results were compiled into JENDL-4.0.
