Using the experimental data of the total cross section, the degenerated scattering cross section, the elastic scattering cross section and the elastic scattering angle distribution of the existing neutron and atomic nucleus Sn and their isotope reactions, a set of universal neutron and Sn and isotope reaction optics Model potential parameters.Using this set of optical model potential parameters, the distorted wave Born approximation theory, the nuclear reaction Hauser Feshbach theory and the pre-equilibrium exciton model, we calculated and analyzed the relationship between neutron and 1 1 6,1 1 8,1 2 0 , 1 2 2, 1 2 4Sn reaction separation of the inelastic scattering cross section and angular distribution of theoretical calculations and experimental data were analyzed and compared
