我们调查的影响变形的可能发生的长寿命的Hf同位素中的$K$异构体约$N=116$，使用配置约束计算的势能面。尽管形状伸长减少，$^{186，188}\mathrm{Hf}$中的多准粒子态对三轴扭曲仍然具有适度的鲁棒性，支持了长期预期的异常长寿异构体的出现。计算结果与现有的实验数据进行了比较。
We investigate the influence of deformation on the possible occurrence of long-lived $K$ isomers in Hf isotopes around $N=116$, using configuration-constrained calculations of potential-energy surfaces. Despite having reduced shape elongation, the multiquasiparticle states in $^{186,188}\mathrm{Hf}$ remain moderately robust against triaxial distortion, supporting the long expected occurrence of exceptionally long-lived isomers. The calculations are compared with available experimental data.
