| 摘 要： | 相对论对称性在原子核的壳层结构及其演化中扮演重要角色.探讨超形变核态的相对论对称性,利用相对论平均场理论计算超形变核态的结合能、单粒子能级,提取单粒子能级的自旋和赝自旋能量劈裂,分析这些能量劈裂与原子核形变及自旋和赝自旋双重态量子数间的关系,进而研究超形变核态的自旋和赝自旋对称性及其随形变变化的规律,结果表明超形变核态的自旋和赝自旋对称性与双重态量子数和形变都相关.

| Abstract: | The relativistic symmetries play an important role in the nuclear shell structure and its evolution.In the paper,the relativistic mean field theory was applied to study the relativistic symmetries in nuclear superdeformed state.With the calculation of the total energy of nuclear superdeformed states,the single particle levels,the energy splitting of spin doublets and that of pseudospin doublets was extracted.By analyzing these energy splittings and their relations with the deformation,it was found that the spin and pseudospin symmetry of the superdeformed nuclei were related to the quantum numbers of the doublets and deformation of the nuclei. |
