Abstract
We determined the experimental value of the g factor of the electron bound in hydrogenlike 28Si13+ by
using a single ion confined in a cylindrical Penning trap. From the ratio of the ion’s cyclotron frequency
and the induced spin flip frequency, we obtain g = 1:995 348 9587 (5)(3)(8). It is in excellent agreement
with the state-of-the-art theoretical value of 1.995 348 958 0(17), which includes QED contributions up to
the two-loop level of the order of (Zα)2 and (Zα)4 and represents a stringent test of bound-state quantum
electrodynamics calculations.
