Neutron Incident I <sup> 127,129,135 </ Sup> Theory Of Reaction Cross Sections Calculated

The cross sections of n+I127, 129, 135 were calculated and analyzed in the energy range from 0. OlMeV up to 20MeV. A set of optimal neutron optical potential parameter is obtained by code APOM for n+O127,129,135 reaction based on the experimental data of total, non-elastic cross sections and elastic scattering distribution. The theoretical results which have been compared with experimental data are in good agreement with existed experimental data. Therefore, this work also demonstrated the reasonability and dependability of theoretical calculation programs. So we say the results show that the theoretical values are in good agreement with the experimental values. The theoretical models are successful. The theoretical model based in our paper is optical model, the semi-classical model of multi-step nuclear reaction processes, the excition model and the distorted wave Born etc. These calculation results have passed through the edition & evaluation and have been accepted into the Evaluation Library by CNDC, and were presented to IAEA to take part in the international comparison.
