Calculation and evaluations for n+63,65,nat.Cu reactions

All cross sections of neutron induced reactions, angular distributions, energy spectra and double differential cross sections are consistently calculated and analyzed for n+63,65,nat.Cu reactions at incident neutron energies below 200 MeV based on the nuclear theoretical models. The optical model, preequilibrium and equilibrium reaction theories, the distorted wave Born approximation theory are used. Theoretical calculated results are compared with existing experimental data and the evaluated results in ENDF/B-VII and JENDL-3 libraries. The optical model potential parameters are obtained according to the experimental data of total, nonelastic scattering cross sections and elastic scattering angular distributions.

► All cross sections of neutron induced reaction, angular distributions and energy spectra are obtained from theoretical models. ► A set of optimal neutron optical potential parameter is obtained up to 250 MeV. ► Theoretically calculated results are in agreement with the existing experimental data.
