论文摘要
在[li $ {\ it et \，al。} $，phys。 Rev. a $ {\ bf 98} $，020502（r）（2018）]据称，羔羊对$^2p_ {1/2}的羔羊转移的模型电位计算，{}^2p_ {}^2p_ {3/2} $ fluorinelike yranium yranium中的细菌结构导致了理论和实验之间的差异。后来，由[volotka $ {\ it et \，al。} $，物理报道。 Rev. a $ {\ bf 100} $，010502（r）（2019）]，{\ it it Ibliox} QED计算，包括一阶单电子QED贡献以及两电子筛选的相关效果，使结果产生了恢复理论与实验和强度分配模型型lamp light faceples之间的结果。在本文中，模型羔羊移动操作员[shabaev $ {\ it et \，al。} $，phys。 Rev. a $ {\ bf 88} $，012513（2013）]用于评估QED对$^2p_ {1/2} - {}^2p_ {3/2} $ fiel-like离子中的良好结构。通过将该操作员纳入采用不同方法的Dirac-Coulomb-Breit方程中来执行计算。可以证明，这些方法基于将羔羊转移算子迁移到狄拉克孔方程中或通过扰动理论中的计算中，导致理论结果彼此彼此吻合并与实验相吻合。 QED效应中这些结果对第一阶的限制会导致一个值，该值与上述$ {\ it ab \，initias} $ QED结果一致。
In [Li ${\it et \, al.}$, Phys. Rev. A ${\bf 98}$, 020502(R) (2018)] it was claimed that the model-potential computations of the Lamb shift on the $^2P_{1/2}-{}^2P_{3/2}$ fine structure in fluorinelike uranium lead to a discrepancy between theory and experiment. Later, it was reported by [Volotka ${\it et \, al.}$, Phys. Rev. A ${\bf 100}$, 010502(R) (2019)] that {\it ab initio} QED calculation, including the first-order one-electron QED contributions and the related effects of two-electron screening, yields the result which restores the agreement between theory and experiment and strongly disagrees with the model-potential Lamb shift values. In the present paper, the model Lamb shift operator [Shabaev ${\it et \, al.}$, Phys. Rev. A ${\bf 88}$, 012513 (2013)] is used to evaluate the QED effects on the $^2P_{1/2}-{}^2P_{3/2}$ fine structure in F-like ions. The calculations are performed by incorporating this operator into the Dirac-Coulomb-Breit equation employing different methods. It is demonstrated that the methods, based on including the Lamb shift operator either into the Dirac-Fock equations or into the calculations by perturbation theory, lead to the theoretical results which are in good agreement with each other and with experiment. The restriction of these results to the first order in the QED effects leads to a value which agrees with the aforementioned ${\it ab\, initio}$ QED result.
