质子与 52 Cr反应数据理论计算与分析

在质子与48Ti，51V和52Cr 反应的去弹截面、弹性散射角分布实验数据的基础上，获得了一组入射质子能量在150 MeV 以下的质子与52Cr 反应的光学势参数。应用光学模型、扭曲波玻恩近似理论、核内级联模型、蒸发模型、带宽度涨落修正的Hauser-Feshbach 理论以及激子模型(含改进的Iwamoto–Harada 模型)计算得到了质子与52Cr 反应的所有截面、角分布、能谱和双微分截面。对理论计算结果与实验数据以及TENDL 中的数据进行了比较分析，结果显示，理论计算结果与实验数据符合较好，且反应道截面优于TENDL的结果。 Based on the experimental data of non-elastic and elastic scattering istributions for p+48V,p+51V and p+52Cr reactions, a set of optical potential parameters for p+52Cr reaction with incident proton energies below 150 MeV are obtained. All cross sections, elastic and inelastic scattering angular distributions,energy spectra and double differential cross sections of six outgoing particles (n, p, d, t, helium-3 and ) for p+52Cr reaction are calculated and analyzed. The optical model, the intra-nuclear cascade model, evaporation model, Hauser-Feshbach theory with width fluctuation correction, exciton model including the improved Iwamoto–Harada model and distorted wave Born approximation theory are involved in the calculation. The calculated results are compared with existing experimental data and the evaluated data from TENDL data base.It is found that our calculated results agree with the experimental data and the calculated cross sections are more consistent with the related experimental data than the results from TENDL data base.
