Perturbation Approach to the Self Energy of non-S Hydrogenic States
Abstract
We present results on the self-energy correction to the energy levels of hydrogen and hydrogenlike ions. The self energy represents the largest QED correction to relativistic Dirac-Coulomb energy levels. We focus on the perturbation expansion of the self energy of non-S states, and provide estimates of the Bethe logarithm and of the so-called A60 perturbative coefficient, which can be considered as a relativistic Bethe logarithm. All non-S atomic states are covered. These results can be used in high-precision spectroscopy experiments in hydrogen and hydrogenlike ions. They yield the best available estimate of the self-energy correction of many atomic states.Keywords
