¹¹B快中子非弹性散射的理论计算

摘要: 本文采用直接作用模型和扭曲波玻恩近似（ＤＷＢＡ）理论，计算了１１Ｂ的２．１４ＭｅＶ激发态在入射中子能量为７：５４～２０．０ＭｅＶ的非弹性散射的积分截面和角分布，计算结果与评价的实验值进行了比较，符合较好．对实验上所缺乏的数据作出了理论预期值． BY using the direct reaction mode and the DWBA theory, We calculate the integrated sections and angular distributions of inelastic neutron scattering of 11B(n, n )11B 2. 14MeV excited state in energy range from 7. 54MeV to 20. 0MeV. The calculated results are comparaed with the experimental values, and a good agreement has been obtained. The theory values are given for absent experimental data.
