| 摘 要： | 在光学势中引入色散关系, 相比于通常的耦合道光学模型, 极大地减少了光学势
参数的个数. 采用基于软旋转子模型的耦合道方法对较轻形变核28Si核的中子和质子散射实验数据进行了计算分析, 拟合得到一组色散光学势参数. 计算的中子总截面、以及中子、质子的弹性与非弹性散射微分截面与实验数据有较好的符合.

| Abstract: | The dispersion relation is included into the optical potential. Compared with the common coupled-channel optical model, the number of potential parameters is greatly reduced. The coupled-channel method based on the soft rotator model is used to analyze the nucleon scattering by a deformed 2ssi nucleus. A set of the optical potential parameters is obtained, and the numerical results show a good agreement with the available experimental data of neutron total cross sections, neutron/proton elastic and inelastic angular distributions. |
