The g-factor of a bound electron has recently gained a lot of experimental as well as theoretical interest.
Comparison between theoretical and experimental results for 12C5+ and 16O7+
led to the determination of the most accurate value of the electron mass [1].
Upcoming experiments [2] with the somewhat heavier ions Si13+ and Ca19+
and beyond are expected to achieve an even greater accuracy, which in turn will call for
accordingly more accurate theoretical predictions. We present theoretical results for medium-Z
hydrogen-like ions with an emphasis on effects arising due to the nuclear structure.
