| 摘 要： | 基于光学模型和带宽度涨落修正的Hauser-Feshbach理论编写了程序OMHFISO,该程序适用于计算靶核处于同质异能态并且入射粒子能量小于5MeV的核反应,入射粒子和出射粒子均可以是n,p,d,t,3He和4He 6种.迄今还很少有人计算过同质异能靶核的全套核数据.利用程序UNF, OMHFISO以及DWUCK4计算了不稳定同位素90Rb和91,93,96,97,98Y的同质异能靶核在入射粒子能量低于20.0MeV的全套中子反应数据, 并且得到了合理的结果.

| Abstract: | A computer code OMHFISO, based on optical model and Hauser-Feshbach theory with width fluctuation correction (WHF), is made for calculating neutron reactions of isomer target below 5MeV, in which both the incoming and outgoing particles can be n, p, d, t, 3He and 4He. Up to now, there are only few people to calculate the complete set of neutron nuclear data of isomer target. In this work, neutron nuclear data of six isomer targets of unstable isotopes 90Rb and 91,93,96,97,98Y are calculated, and reasonable results in physics are obtained. |
