Theoretical calculations and analysis of n+208Pb reaction for intermediate energy neutron

Based on experimental data of total, nonelastic, elastic cross section and elastic scattering angular distributions for n + Pb reactions, a set of neutron optical model potential parameters is obtained in the region of incident neutron energy from 1-300 MeV. The cross sections angular distributions and energy spectra are calculated and analyzed by optical model, distorted wave born approximation theory, Hauser-Feshbach theory, exciton model and cascade mechanism inside nuclear. The results indicate that the cross sections can be given for n + 208Pb reactions which are all in good agreement with experimental data
