论文摘要
我们报告了对类似于李的离子基$ g $因子的自我能力筛选效果的调查。相对订单$ 1/z $的领先筛选贡献均计算为结合核强度参数$zα$中的所有订单（其中$ z $是核电数量，而$α$是精细结构常数）。我们还通过得出$α^5 \lnα$的领先对数贡献，并获得$α^5 $和$α^6 $贡献的近似结果，从而扩展了QED筛选校正的$Zα$扩展的已知结果。两种方法的比较得出了两种计算的一致性的严格检查，并使我们能够获得更高的高阶筛选效果的估计。
We report an investigation of the self-energy screening effects for the $g$ factor of the ground state of Li-like ions. The leading screening contribution of the relative order $1/Z$ is calculated to all orders in the binding nuclear strength parameter $Zα$ (where $Z$ is the nuclear charge number and $α$ is the fine-structure constant). We also extend the known results for the $Zα$ expansion of the QED screening correction by deriving the leading logarithmic contribution of order $α^5\lnα$ and obtaining approximate results for the $α^5$ and $α^6$ contributions. The comparison of the two approaches yields a stringent check of consistency of the two calculations and allows us to obtain improved estimations of the higher-order screening effects.
