论文摘要
在严格的QED方法的框架内考虑了核后坐力对原子和离子的核后坐力对原子结合能的一部分部分对一阶的电子相互作用校正。 $αz$中所有订单的计算均以$ 1S^2 $状态的氦离子和$ 1S^2 2s $和$ 1S^2 2p_ {1/2} $ state的lithiumlike ions in Lithiumlike Ions的范围$ z = 5 $ 100 $。将获得的结果与Breit-approximation值进行了比较。执行的计算完成了对QED核后坐力效果的系统处理，最高为$ 1/z $。获得的校正与先前研究的两电子部分以及在BREIT近似中评估的高阶电子相关校正结合在一起，以获得质量变化的总理论预测。
The electron-electron interaction correction of first order in $1/Z$ to the one-electron part of the nuclear recoil effect on binding energies in atoms and ions is considered within the framework of the rigorous QED approach. The calculations to all orders in $αZ$ are performed for the $1s^2$ state in heliumlike ions and the $1s^2 2s$ and $1s^2 2p_{1/2}$ states in lithiumlike ions in the range $Z=5$--$100$. The results obtained are compared with the Breit-approximation values. The performed calculations complete a systematic treatment of the QED nuclear recoil effect up to the first order in $1/Z$. The correction obtained is combined with the previously studied two-electron part as well as the higher-order electron-correlation corrections evaluated within the Breit approximation to get the total theoretical predictions for the mass shifts.
