Calculation and Analysis of n + ^{112,114-120,122,124,nat}Sn Reactions

Through experimental data of total, nonelastic scattering, elastic scattering cross sections, and elastic scattering angular distributions of Sn, a set of neutron optical model potential parameters is obtained. All reaction cross sections, angular distributions, energy spectra, gamma-ray production cross sections, gamma-ray production energy spectra, especially, the double-differential cross section for neutron, proton, deuteron, triton, and alpha emission, and inelastic scattering cross sections and inelastic scattering angular distributions for low-lying residual nucleus states are calculated and analyzed for n + ^{112,114-120,122,124,nat}Sn at incident neutron energies from 0.1 to 20 MeV based on measured data and the nuclear model theory, which are an optical, semiclassical model of multistep nuclear reaction processes and distorted-wave Born approximation theory. Theoretical calculations are compared with existing experimental data and other evaluated data from JENDL-3.
