摘要
本文从壳模型组态和核子—核子相互作用出发 ,借助Dyson玻色子展开 ,MJS代换和适当定义的具有很强集体性的玻色子 ,阐述了sdgIBM理论的一种微观方案 .以13 2 Xe为对象 ,计算了能谱和跃迁几率 ,与最近的实验数据比较表明 :该理论适合于描述原子核的低能集体运动 ,而且确认该核属类O( 6 )
One of kinds of microscopic approach on sdgIBM-2 theory is described in this paper, starting from the configuration of nuclear shell model and nucleon-nucleon interaction, by means of Dyson boson expanding, MJS substitution, and appropriate defined Boson having quite strong collectivity. Energy spectrum and transition probability of 132 Xe nucleus are calculated and compared with recent experimental data , which shows that the above approach is suitable for description nuclear collective motion , and 132 Xe nucleus is established as quasi-O(6) nuclei .
