The analysis of n+237Np reactions for energies up to 200 MeV

Abstract All cross sections, angular distributions, energy spectra and double differential cross sections of neutron, proton, deuteron, triton, alpha-particle emission and the prompt fission neutron spectra for n+ 237 Np reactions are consistently calculated and analyzed. The optical model, the intra-nuclear cascade model, the unified Hauser–Feshbach theory and the exciton model which includes the improved Iwamoto–Harada model, the fission model, the linear angular momentum dependent exciton density model and the distorted wave Born approximation theory are used in the energy range of E n  ⩽ 200 MeV. Theoretical calculations are compared with recent experimental data and other evaluated data from ENDF/B-VII and JENDL-3.
