论文摘要
在持续到我们较早报道的有关电偶极子(E1)矩阵元件的数据以及[原子数据和NUC中碱性地球离子的亚稳态状态的寿命。数据表{\ bf 137}(2021)101381],我们在这里介绍Mg $^+$,CA $^+$,SR $^+$和BA $^+$^+$ alkaline Earter-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal-Metal Ions在这里提出的调音和魔术波长。此外,我们已经评估了使用全阶相对论多体方法的大量禁止过渡的电力四极(E2)矩阵元素,并将它们与一些选择性过渡的先前报道的值进行了比较。 E1和E2过渡矩阵元素的汇编现在将提供有关被考虑的单一带电碱接地离子的过渡特性的更完整的知识。同样,由于主要的E1极化能力,使用上述系统降低系统的离子进行实验,因此列出的调节和魔术波长的精确值可能有助于进行实验。因此,所有这些数据对于在原子物理学中进行高精度实验和实验室模拟以及在天体物理观察中解释过渡线的各种应用将非常有用。
In continuation to our earlier reported data on the electric dipole (E1) matrix elements and lifetimes of the metastable states of the alkaline earth ions in [Atomic Data and Nuc. Data Tables {\bf 137} (2021) 101381], we present here the tune-out and magic wavelengths of the Mg$^+$, Ca$^+$, Sr$^+$ and Ba$^+$ alkaline earth-metal ions by determining dynamic E1 polarizabilities. Furthermore, we have evaluated the electric quadrupole (E2) matrix elements of a large number of forbidden transitions using an all-order relativistic many-body method and compare them with the previously reported values for a few selective transitions. Compilation of both the E1 and E2 transition matrix elements, will now provide a more complete knowledge about the transition properties of the considered singly charged alkaline earth-metal ions. Similarly, the listed precise values of tune-out and magic wavelengths due to the dominant E1 polarizabilities can be helpful to conduct experiments using the above ions with reduced systematics. Therefore, all these data will be immensely useful for various applications for carrying out the high-precision experiments and laboratory simulations in atomic physics, and interpreting transition lines in the astrophysical observations.
