Description
QED effects associated with the electron self-energy and vacuum polarization are calculated in non-Coulomb potentials for atomic states with principal quantum numbers 1 and 2. We consider the Coulomb potential with finite nuclear size incorporated and using the core-Hartree potential, a local version of the Hartree-Fock potential. The calculations are carried out for ions with nuclear charges in the range Z=60--90. For the Coulomb potential with finite nuclear size, substantial discrepancies with an earlier tabulation are found. Radiative corrections are calculated for lithiumlike uranium using the core-Hartree potential and comparison with experiment is made
