Theoretical Calculations Of Reaction Cross Sections Of Neutron Incident N + Ga ~ (67,71, Nat)

All cross sections neutron induced reaction elastic scattering angular distribution, neutron energy spectrum and double differential cross sections of n+Ga69,71,Nat were calculated and analyzed by using optical model and the semi-classical model of multi-step nuclear reaction processes based on the Hauser-Feshbach theory and the exciton model in the energy region up to 20MeV. A set of optimal neutron optical potential parameters are obtained by the code APOM for n+Ga69,71 reaction based on the experimental data of total, non-elastic cross sections and elastic scattering distribution. The abundance of the each isotopes should be considered in calculating the reaction of n+GaNat. Since the recoil effect is taken into account, the energy for whole reaction processes is balance. The calculated results indicate that the theoretical results which have been compared with experimental data are in good agreement with existed experimental data, and it is successful to predict nuclear reaction by using optical model and the semi-classical model of multi-step nuclear reaction processes in theory.Bi zhen ( Theoretical Physics) Directed by Professor Sun xiu-quan...
