- New estimates of partial α-decay half-life, $T_{1/2}$, for ^{156–162,174,176}Hf isotopes by a semi-empirical, one-parameter model are given. The used model is based on the quantum mechanical tunneling mechanism through a potential barrier, where the Coulomb, centrifugal and overlapping components to the barrier have been considered within the spherical nucleus approximation. This approach enables to reproduce, within a factor 2, the measured $T_{1/2}$ of ground-state to ground-state (gs–gs) α-transitions for the artificially produced ^156–162Hf isotopes. Half-life predictions for α-transitions from the ground-state of ^159,161Hf isotopes to the first gamma-excited level of ^155,157Yb isotopes are reported for the first time. The model also provides $T_{1/2}$-values of $\left(2.43\pm 0.28\right)\times {10}^{16}$ a and $\left(1.47\pm 0.19\right)\times {10}^{20}$ a for the naturally occurring ¹⁷⁴Hf and ¹⁷⁶Hf isotopes, respectively, in quite good agreement with a number of estimates by other authors. In addition, the present methodology indicates that ^174,176Hf isotopes exhibit α-transition to the first gamma-excited level of their daughter Ytterbium isotopes which half-lives are found $\left(0.9\pm 0.1\right)\times {10}^{18}$ a and $\left(0.72\pm 0.08\right)\times {10}^{22}$ a, respectively, with a chance of being measured by improved α-detection and α-spectrometry methods available nowadays.

-部分α衰变半衰期的新估计，${Ť}_{\mathrm{1个}/2}$^给出了半经验的一参数模型对^{156–162,174,176} Hf同位素的分析结果。使用的模型基于通过势垒的量子力学隧穿机制，其中已在球形核近似中考虑了库仑，离心和与该垒的重叠分量。这种方法能够在因子2内重现所测得的${Ť}_{\mathrm{1个}/2}$人工产生的^156-162 Hf同位素的基态到基态（gs-gs）α跃迁的变化。首次报道了从基态^159,161 Hf同位素到第一伽马激发水平^155,157 Yb同位素的α跃迁的半衰期预测。该模型还提供${Ť}_{\mathrm{1个}/2}$的值 $（2.43\pm 0.28）\times {10}^{16}$ 和 $（1.47\pm 0.19）\times {10}^{20}$天然存在的¹⁷⁴ Hf和¹⁷⁶ Hf同位素的a，与其他作者的大量估计非常吻合。此外，本方法学表明，^174,176个f同位素具有向其子级Y同位素的第一个伽马激发能级的α-跃迁，该半衰期被发现$（0.9\pm 0.1）\times {10}^{\mathrm{18岁}}$ 和 $（0.72\pm 0.08）\times {10}^{22}$ 分别通过当今可用的改进的α检测和α光谱法进行测量。
