摘要:

本文严格地计算了类铍离子的基态的电离能。计算合并从头计算QED治疗的第一和第二阶的微扰理论中的精细结构常数$α$与第三和更高阶的电子相关的贡献内Breit近似评估。考虑了核反冲和核极化效应。与以前的计算相比,得到的电离能的准确性已显着提高。

英文摘要:

Ionization energies for the ground state of berylliumlike ions with nuclear charge numbers in the range Z=16-96 are rigorously evaluated. The calculations merge the ab initio QED treatment in the first and second orders of the perturbation theory in the fine-structure constant $α$ with the third- and higher-order electron-correlation contributions evaluated within the Breit approximation. The nuclear recoil and nuclear polarization effects are taken into account. The accuracy of the ionization energies obtained has been significantly improved in comparison with previous calculations.
