摘要

提出了一种考虑到集体变量变化区间限制的简单半解析集体模型来描述具有固定粒子-空穴构型的三轴奇-奇核的手性动力学。集体哈密顿量是用对相对于手性变换对称的波函数的假定方差得到的势能来构造的。通过对角化集体哈密顿量，得到了最低态的波函数，并证明了手性重态从手性振动向手性旋转过渡时能量分裂的演化过程。

Simple collective model for nuclear chiral mode

A simple semi-analytical collective model that takes into account the limitations of the variation interval of the collective variable is suggested to describe the chiral dynamics in triaxial odd-odd nuclei with a fixed particle–hole configuration. The collective Hamiltonian is constructed with the potential energy obtained using the postulated ansatz for the wave function symmetric with respect to chiral transformation. By diagonalizing the collective Hamiltonian the wave functions of the lowest states are obtained and the evolution of the energy splitting of the chiral doublets in transition from chiral vibration to chiral rotation regime is demonstrated.
