| Abstract: | By fitting the experimental data of total, innelastic and elastic scattering angular distributions for n+Cu reactions, a set of neutron optical model potential parameters is obtained. The inelastic scattering angular distributions of discrete levels and double differential cross sections are calculated and analyzed by using the distorted wave Born approximation theory, the unified Hauser-Feshbach model and the exciton model. By fitting data the neutron level deduced deformation parameters are obtained. The results indicate that the calculated results of the inelastic scattering angular distributions and the total outing neutron double-differential cross sections for n+63,65Cu can be obtained, which are all in good agreement with the experimental data. |
