Coordinatespace approach to the boundelectron selfenergy: Selfenergy screening calculation
Abstract
The selfenergy screening correction is evaluated in a model in which the effect of the screening electron is represented as a firstorder perturbation of the selfenergy by an effective potential. The effective potential is the Coulomb potential of the spherically averaged charge density of the screening electron. We evaluate the energy shift due to a 1s_{1/2}, 2s_{1/2}, 2p_{1/2}, or 2p_{3/2} electron screening a 1s_{1/2}, 2s_{1/2}, 2p_{1/2}, or 2p_{3/2} electron, for nuclear charge Z in the range 5<=Z<=92. A detailed comparison with other calculations is made.
