-
摘要: 该工作利用现有的实验数据对天然铁~NFe(包括~(54)Fe,~(56)Fe和~(57)Fe)在中子入射能量为0.1-20 MeV范围内的中子反应数据进行了计算。采用的理论模型是光学模型、带宽度涨落修正的Hauser-Feshbach理论(WHF)以及包括预平衡发射的蒸发模型(YPH)。无论是天然元素还是同位素,理论计算结果和实验数据符合尚好。Abstract: Based0on present experimental data, the data for neutron-induced reactions on ~(54,56,57)Fe and ~NFe are calculated employing several nuclear models——the optical model, the Hauser-Feshbach theory with width fluctuation, and the evaporation with the pre-equilibrium exciton model in the energy range between 0. 1 and 20 MeV. The extensive comparisons with experimental data are given. The agreement between the calculated results and experimental values seems to be satisfactory.
