The effects of taking into account the Breit interaction to all orders by including it in the self-consistent field process are demonstrated. State of the art radiative corrections are included in the calculation and discussed. We also study the non-relativistic limit of MCDF calculation and find that the non-relativistic offset can be unexpectedly large.engSuperheavy elementsQED correctionsLandé g-factorsatomic radiiBreit interactionMCDFjournal article
