^(168)Hf三轴超形变核态的研究

Study of Triaxial Superdeforrnation in ^(168)Hf

采用TRS方法研究了168Hf核的三轴超形变核态．通过位能面计算给出了平衡形变参数,证实了高自旋态下该核存在三轴不对称性．通过分析各部分修正能量,研究了其三轴超形变形成的机制:主要原因是中子壳修正,同时高j闯入轨道πi13／2的形变驱动效应和转动能也起到重要作用．

A Total Routhian Surface（TRS） calculation are performed for studying triaxial superdeformation in the ^168Hf nuclei. The equilibrium deformation parameters are given. The shell and pairing correction energies are considered respectively, the formation mechanism of triaxial superdeformation is investigated. The large deformation is due to the neutron shell correction energy and high j intruder orbital πi13/2.
