摘要: 介绍裂变核光学模型参数自动调节程序ASOP以及用它寻求~(235)U和~(239)Pu两个核的最佳光学热势参数所得到的结果。计算表明由ASOP得到的最佳光学势参数优于申庆彪给出的最佳光学势参数。尤其是在10 keV至3 MeV能段,由ASOP算出的裂变截面、辐射俘获截面、去弹截面和全截面与实验值的条例程度都明显地好于由申氏参数算得的结果。Abstract: In the paper, author outline the program ASOP and give the optimal optical potential parameters of U-235 and Pu-239 obtained by ASOP as well as the calculated results from them. The optimal optical potential parameters obtained by ASOP are better than Shen's. The calculated σ_(nf), σ_(nγ),σ_(non) and σ_1 from our parameters are all obviously better than those from Shen's parameters, especially in 10 keV—3 MeV energy region.
