针对核物理近年来出现的手征对称性和摇摆运动等热点问题,介绍具有微观基础的集体哈密顿量理论的研究进展.首先,简要回顾手征对称性和摇摆运动的研究现状.接着,给出基于倾斜轴推转模型,构建微观集体哈密顿量理论的具体过程.随后,介绍新发展的集体哈密顿量理论对于手征对称性和摇摆运动的研究.具体包括:介绍手征双重带能量差随转动频率变化的微观机制的研究,给出了手征双重带能量差随转动频率逐渐减小,是双中心势势垒的逐渐增高抑制手征伙伴态之间量子隧穿的结论;介绍简单、纵向、横向3类摇摆运动的摇摆频率随转动频率演化的微观机制,得到了摇摆频率的演化趋势与集体势的软硬度相关的结论.
Aiming at the hot issues such as chiral symmetry and swinging motion in recent years, this paper introduces the research progress of the micro-basis collective Hamiltonian theory.Firstly, the current research on the chiral symmetry and the swinging motion is briefly reviewed.Then, The concrete process of constructing the micro-collective Hamiltonian theory is presented based on the model of tilting axis pushover.Then, the new development of the collective Hamiltonian theory for the study of chiral symmetry and swinging movement is introduced, including the introduction of the energy of the chiral double band Difference with the change of the rotational frequency of the microscopic mechanism of the study, given the chiral double band energy difference with the rotation frequency decreases, the double center potential barrier is gradually increased inhibition of chiral partner state between the quantum tunneling conclusion; Introduction The microscopic mechanism of the swing frequency of the three kinds of simple, vertical and horizontal rocking movements with the evolution of the rotating frequency obtained the conclusion that the evolutionary tendency of the rocking frequency is related to the soft and hard of the collective potential.
