Extraction of the electron mass from $g$ factor measurements on light hydrogenlike ions

Atomic Physics 2017-07-12 v1 Quantum Physics

Abstract

The determination of the electron mass from Penning-trap measurements with 12^{12}C5+^{5+} ions and from theoretical results for the bound-electron gg factor is described in detail. Some recently calculated contributions slightly shift the extracted mass value. Prospects of a further improvement of the electron mass are discussed both from the experimental and from the theoretical point of view. Measurements with 4^4He+^+ ions will enable a consistency check of the electron mass value, and in future an improvement of the 4^4He nuclear mass and a determination of the fine-structure constant.
