质子与裂变核^(238)U反应的理论计算

Theoretical Calculations for p+^(238) U Reactions

利用球型光学模型、耦合道理论、核内级联、激子模型、蒸发模型、带宽度涨落修正的Hauser Feshbach模型 ,Bohr Wheeler裂变理论 ,对入射能量从阈能到 2 0 0MeV的p + 2 38U各种反应进行了计算 ,计算结果和实验符合较好 .

Based on the spherical optical model, the Coupled-Channels theory, the empirical formula based intranuclear cascade mechanism for nucleon emission, the exciton model, the evaporation model and the Hauser-Feshbach statistical theory with width fluctuation correction, the reaction data are calculated for p + 238U in the energy region from threshold up to 200 MeV, the fission widths are calculated with Bohr-Wheeler formula. The calculated results are generally in good agreement with the experimental data.
