Abstract
The Breit interaction has been treated together with the Coulomb interaction in a self-consistent way, leading to modified occupied orbitals (Dirac-Fock-Breit orbitals), which are analysed. The arguments against the inclusion of the Breit interaction to higher orders are discussed, as well as the advantages in doing so. The new orbitals are then used to calculate the electric dipole moment (EDM) in Tl and are found to lead to a 2% reduction of the EDM enhancement factor.Keywords
