Abstract.
The influence of quantum electrodynamic (QED) corrections on the valence electrons in superheavy atoms with nuclear charge Z ≈112 is studied within the effective local-potential approximation and the self-consistent approach. The results are obtained from a relativistic coupled-cluster calculation without inclusion of QED effects. The difference between the effective-potential and the self-consistent approach for the leading QED correction to the energy of the valence-electron levels in any superheavy atoms defines an inaccuracy of about \(0.1\%\) of the first ionization potential.
