| 摘 要： | 在推转壳模型的基础上,本文用粒子数守恒方法分析讨论了Er_(96),Er_(98)的低激发带的相互作用强度V_I和带交叉频率ωc。单粒子能级选用国际上通用的尼尔逊能级,参数按Lund系统学选取。计算表明,Er_(96)的V_I较小,属于弱耦合;Er_(98)的V_I较大,属于强耦合,这些与实验是相符的,即Er_(96)存在尖锐回弯,Er_(98)则没有回弯,但Er_(96)的ωc比实验值大,为了进一步改进其结果,木文对相互作用问题作丁尝试性的探讨,使其结果有所改进。

| Abstract: | The eigenvalue problems of the CSM (Cranked Shell Model) Hamiltonian for Er96, Er98 were solved by the PNC (Particle Number Conserving) method. The paper discussed the low-lying energy spectra, especially the interaction strength VI and band cross frequency ?c. Nilsson level was adopted to single particle level and the parameters were chosen according to the Lund system. It is found that VI of Er98 is small, belonging to weak coupling, but the VI of Er98 is big, belonging to strong coupling. All of these results are reproduced with experiments in which Er98 has no back bendings and Er96 has a sharp back bending in thear2a of ?/?0~0.2. In order to improve the results of band cross frequency ?c of Er96, this paper goes further in the study of the problems of pair interaction strength. |
