P. Indelicato et Pj. Mohr, Coordinate-space approach to the bound-electron self-energy: Self-energy screening calculation - art. no. 052507, PHYS REV A, 6305(5), 2001, pp. 2507
The self-energy screening correction is evaluated in a model in which the e
ffect of the screening electron is represented as a first-order perturbatio
n of the self-energy by an effective potential. The effective potential is
the Coulomb potential of the spherically averaged charge density of the scr
eening 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 t
han or equal to 92. A detailed comparison with other calculations is made.
