| 摘 要： | 利用形变约束的相对论平均场理论系统研究了Mo同位素链偶-偶核的形状演化,比较了基态结合能和四极形变的理论计算值和实验值,并详细分析了这些核的位能曲线和单粒子能级,发现随着中子数的增加,Mo同位素链的基态形变向γ不稳定形变方向演化,94Mo是γ不稳定核,与实验结果一致.

| Abstract: | The shape phase transition between spherical U(5) and γ-unstable O(6) was investigated systematically for Mo isotopes in the microscopic quadrupole constrained relativistic mean field(RMF) model plus BCS method with all the most used interactions,ie.,PK1,NL3,TM1,TMA. The calculated potential energy surfaces showed a clear shape transition for the even-even Mo isotopes with N=50-64 and ~(94)Mo was suggested to be the γ-unstable nuclei, which was favored by the experiments. |
