Abstract

The self-energy screening correction is evaluated in a model in which the effect of the screening electron is represented as a first-order perturbation of the self-energy by an effective potential. The effective potential isthe 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 less than or equal toZ less than or equal to 92. A detailed comparison with other calculations is made.
