Comparative study of the nuclear-polarization corrections in highly charged ions — •Andrey Volotka and Günter Plunien — Institut für Theoretische Physik, TU Dresden

A systematic investigation of the nuclear-polarization effects in one- and few-electron heavy ions is presented. The nuclear-polarization corrections in the zeroth and first orders in 1/Z have been evaluated to the binding energies, the hyperfine splitting, and the bound-electron g factor. The effect of the nuclear polarization has been investigated for the specific differences constructed in a way to cancel the nuclear size corrections. In all cases considered, it has been demonstarted, that the nuclear-polarization contributions can be substantially canceled simultaneously with the rigid nuclear corrections [1]. Therefore, the rigorous investigations of the specific differences provide a unique opportunity to test the strong-field QED with a much higher accuracy than expected before.
