摘要
利用推转壳模型(CSM)的粒子数守恒(PNC)处理方法,分析了^(166-176)Yb偶偶核基带转动惯量随中子数变化的微观机制。仔细分析了CSM的PNC波函数的K结构和seniority结构。低激发高j闯入K~π=1^+组态的分布对转动惯量值有决定性影响。
Using the particle-number-conserving (PNC) method, the microscopic mechanism of the variation of the ground band moments of inertia with neutron numbers in ^(166-176)Yb is investigated in the cranked shell model (CSM). The K-structure and seniority structure of the PNC CSM wave function are analyzed carefully. The distribution of the low-lying high-j intruder pair-broken (υ=2)κ~π=1^+ configurationsplays a crucial role for the magnitude of the ground band moments of inertia.
