First-principle calculations based on the density functional theory (DFT) method are adopted to investigate the influence of a strong electric field on the ⁷Be half-life. Accordingly, electronic structures of Be and BeO are examined in the presence of a homogeneous electric field. The electron density at the nucleus is estimated upon the geometry optimization. Our computations for the Be metal indicate a 0.02% increase in the decay rate of the ⁷Be nucleus, corresponding to a 0.02% decrease in the ⁷Be half-life, both at 5.14 V/ (0.1 a.u.). Furthermore, it is determined that the decay rate of ⁷Be is not considerably altered up to 3.6 V/ in the BeO structure. Our results show that the screening energy of the electron can be dependent on the applied electric field strength. Furthermore, we predict variations in the Coulomb potential at the ⁷Be nucleus due to electric field application.

采用基于密度泛函理论（DFT）方法的第一性原理计算来研究强电场对⁷ Be 半衰期的影响。因此，在存在均匀电场的情况下检查 Be 和 BeO 的电子结构。根据几何优化估计原子核处的电子密度。我们对 Be 金属的计算表明⁷ Be 原子核的衰变率增加了 0.02% ，对应于⁷ Be 半衰期减少 0.02% ，均为 5.14 V/ (0.1 au)。此外，确定衰减率为⁷在 BeO 结构中，Be 在高达 3.6 V/ 时没有显着改变。我们的结果表明，电子的屏蔽能取决于施加的电场强度。此外，我们预测了⁷ Be 原子核的库仑电位因电场应用而发生的变化。
