QED theory of the specific mass shift in few-electron atoms
QED theory of the specific mass shift in few-electron atoms
Calculations of the two-electron QED recoil contributions to the binding energies of few-electron ions are extended to the limit of interelectronic-interaction correction, i.e., surpassing the standard independent-electron approximation. The results will allow one to improve the theoretical accuracy of the mass shift calculations in highly charged ions, helping to solve …
