Two-Loop Effects and Current Status of the 4He+ Lamb Shift

Abstract

We report on recent progress in the treatment of two-loop binding corrections to the Lamb shift, with a special emphasis on S and P states. We use these and other results in order to infer an updated theoretical value of the Lamb shift in 4He+.
