Abstract
The determination of the electron mass from Penning- trap measurements with C-12(5+) ions and from theoretical results for the bound- electron g 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 points of view. Measurements with He-4(+) ions will enable a consistency check of the electron- mass value, and in the future an improvement of the He-4 nuclear mass and a determination of the fine-structure constant.
