摘　　要：本文在相互作用玻色子模型框架下对偶–偶核100Zr进行了理论研究。绘制了基态带的E-GOS曲线,讨论其动力学对称性极限性质,数据分析表明100Zr是具有U(5)振动极限到SU(3)转动极限之间的过渡核,趋近于O(6)极限。同时文中也拟合了100Zr核的低能谱的谱带,并对波函数结构进行了理论研究,计算了100Zr核的低能谱部分的电磁跃迁,计算结果表明理论计算与实验值符合较好。Even-even nuclei 100Zr were studied within the framework of the interacting boson model. The E-Gamma Over Spin (E-GOS) was drawn, and the analysis of the dynamic symmetry limit found that 100Zr is a transition nuclei from U(5) vibrational limit to SU(3) rotational limit , close to O(6) dynamic symmetry limit. At the same time, the energy spectrum of low-lying states of 100Zr was fitted, the components of the wave function were analyzed, and the B(E2) values of transitions between low-lying states of 100Zr were analyzed respectively. The results show good agreement with the available experimental data.
