摘要

目前的工作是探索γ-软度对三轴奇-奇核中π - h11/2ν - h11/2粒子-空穴组态上建立的伙伴能带的影响。给出了用岩心-粒子-空穴耦合进行的计算结果。模型哈密顿量包括集体核、单粒子价核子和可分离的四极-四极相互作用。采用Kerman-Klein方法寻找特征态,为探索核心效应提供了方便的途径。采用通用集体模型对具有不同γ-柔软度的三轴岩心进行了计算,三轴参数的期望值固定为(γ)=30°。π - h11/2ν - h11/2的简并性来自于γ-刚性核的计算,而γ-不稳定核的简并性被提升。

Triaxiality, chirality and γ-softness
Current work explores the impact of γ-softness on partner bands built on the πh11/2νh11/2 particle-hole configurations in triaxial odd-odd nuclei. The results of calculations conducted using a core-particle-hole coupling are presented. The model Hamiltonian includes the collective core, the single-particle valence nucleons, and separable quadrupole-quadrupole interactions. The Kerman-Klein method was applied to find eigenstates, which provided a convenient way for exploring core effects. Calculations were made for triaxial cores with various γ-softness using the General Collective Model keeping the expectation value for the triaxiality parameter fixed at (γ)=30°. The degeneracy in the πh11/2νh11/2 bands results from the calculations for the γ-rigid core but is lifted for the γ-unstable core.
