受到最近在富中子核 108Zr 中半衰期为 (620150) ns 的新异构体的实验启发，我们应用具有轴向变形基底的投影壳模型来讨论接近基态的可能形状和异构体的性质。通过将计算限制在长长形和扁圆形形状来研究新异构体的结构。表明该异构体可以理解为K-异构体。同时，计算预测了更多低位高K构型，这可能会被未来的实验所证实。
Inspired by the recent experimental identification of the new isomer with a half-life of (620150) ns in the very neutron-rich nucleus 108Zr, we apply the projected shell model with axially-deformed bases to discuss possible shapes near the ground state and the nature of the isomer. The structure of the new isomer is investigated by restricting the calculation to prolate and oblate shapes. It is shown that the isomer can be understood as a K-isomer. Meanwhile, the calculation predicts more low-lying high-K configurations, which may be confirmed by future experiments.
