论文摘要
我们使用辐射潜在方法对重碱原子RB，CS，FR和碱基类离子SR+，BA+，BA+，BA+，BA+和RA+RA+和RA+RB，CS，FR和RA+。通过与简单原子电位中严格的QED的结果进行比较来检查该方法的有效性。我们研究了核心松弛，核心通过E1场对核心的极化以及对QED的价核相关性的影响，在某些情况下，这在某些情况下很重要。我们确定了QED贡献超过原子理论与实验之间偏差的几种过渡。
We use the radiative potential method to perform a detailed study of quantum electrodynamics (QED) radiative corrections to electric dipole (E1) transition amplitudes in heavy alkali-metal atoms Rb, Cs, Fr, and alkali-metal-like ions Sr+, Ba+, and Ra+. The validity of the method is checked by comparing with the results of rigorous QED in simple atomic potentials. We study the effects of core relaxation, polarization of the core by the E1 field, and valence-core correlations on QED, which are shown to be important in some cases. We identify several transitions for which the QED contribution exceeds the deviation between atomic theory and experiment.
