摘要

摘要: 本工作通过理论计算的方法获得了一套适合入射能量为从阈值到200 MeV的p+^107,109Ag核反应全套微观数据。首先，使用光学模型理论进行调参计算，得到了一套适合入射能量为从阈值到340 MeV的p+^107,109Ag核反应Becchetti-Greenlees光学势参数，这套参数与实验数据符合很好。其次，在这套光学势参数的基础上用扭曲波玻恩近似对入射能量从阈值到200 MeV的p+^107,109Ag直接非弹性散射截面进行了计算。最后，使用核反应统计理论计算了入射能量从阈值到200 MeV的p+^107,109Ag核反应各反应道的截面和出射粒子能谱，得到了该能区p+^107,109Ag核反应全套微观数据。将所有计算值与实验数据进行比较，结果表明，所得到的全套微观数据与实验数据符合很好。

Abstract: The full set of micro data for p+^107,109Ag nuclear reaction with incident energy from threshold up to 200 MeV was obtained by theoretical calculation. Firstly, a set of Becchetti-Greenlees optical model potential parameters for p+^107,109Ag nuclear reaction with incident energy from threshold up to 340 MeV was obtained using optical model theory. The set of parameters is in good agreement with the experimental data. Secondly, based on this set of parameters, the cross sections of inelastic scattering for p+^107,109Ag nuclear reaction with incident energy from threshold up to 200 MeV were calculated using distorted wave Born approximation theory. Thirdly, all the cross sections and energy spectra for p+^107,109Ag nuclear reaction with incident energy from threshold up to 200 MeV were calculated using intra-nuclear cascade model and nuclear reaction statistical theory. Finally, all the calculation data were compared with the experimental data respectively and the results show that the full set of micro data is in good agreement with the experimental data.
