| Abstract: | Based on nuclear reaction models, i.e., the optical model, evaporation model, exciton model and the direct reaction theory, cross sections of (p, x n) reactions and residual nuclei productions for p+ 209 Bi reaction were calculated in energy region from threshold up to 300MeV and a set of proton optical potential parameters for 209 Bi up to 500MeV were obtained. The direct inelastic cross sections were calculated with the distorted wave Born approximation theory. Theoretical results show that the direct inelastic cross sections of about 550mb are reasonable. |
