摘要

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+²³⁷Np 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 猢?#xA0;200 MeV. Theoretical calculations are compared with recent experimental data and other evaluated data from ENDF/B-VII and JENDL-3.
