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．
The introduction of dispersion in the optical potential, compared to the usual coupling optical model, greatly reduces the number of optical potential parameters. The neutron and proton scattering experimental data of 28 SU core nuclei of lighter deformed nuclei are calculated and analyzed by the coupled track method based on the soft rotors model. A set of dispersive optical potential parameters are obtained. The calculated total neutron cross section, as well as the neutron, proton elastic and inelastic scattering differential cross section with the experimental data are in good agreement.
