粒子-空穴组态三轴核高激发带的手征几何

Chiral geometry of higher excited bands in triaxial nuclei with particle-hole configuration

Q. B. Chen, J. M. Yao, S. Q. Zhang, B. Qi

摘要:

在粒子-转子模型中,研究了具有不同三轴度参数$γ$和粒子-孔结构$πh^1_{11/2}\otimesνh^{-1}_{11/2}$的最低六个转动带。介绍了常惯性矩和自旋相关的变惯性矩。计算了能谱、电磁跃迁几率、角动量分量和$K$分布。结果表明,除了带1和带2外,用$γ=30^\circ$计算原子核的CMI和VMI时所预测的带3和带4都可以解释为手征双重带。

英文摘要:

The lowest six rotational bands have been studied in the particle-rotor model with the particle-hole configuration $πh^1_{11/2}\otimesνh^{-1}_{11/2}$ and different triaxiality parameter $γ$. Both constant and spin-dependent variable moments of inertial (CMI and VMI) are introduced. The energy spectra, electromagnetic transition probabilities, angular momentum components and $K$-distribution have been examined. It is shown that, besides the band 1 and band 2, the predicted band 3 and band 4 in the calculations of both CMI and VMI for atomic nuclei with $γ=30^\circ$ could be interpreted as chiral doublet bands.
