Determination of the electron's mass from g-factor experiments on 12C5+ and 16O7+

We present a derivation of the electron's mass from our experiment on the electronic g factor in C-12(5+) and O-16(7+) together with the most recent quantum electrodynamical predictions. The value obtained from C-12(5+) is m(e) = 0.0005485799093(3) u, that from oxygen is m(e) = 0.0005485799092(5) u. Both values agree with the currently accepted one within 1.5 standard deviations but are four respectively two-and-a-half times more precise. The contributions to the uncertainties of our values and perspectives for the determination of the fine-structure constant alpha by an experiment on the bound-electron g factor are discussed.
