Bound-electron g factor of highly charged ions — •Andrey Volotka — Helmholtz-Institut Jena, D-07743 Jena, Germany

In recent years, remarkable progress in experimental and theoretical investigations of the bound-electron g factor of highly charged ions has been achieved. In particular, it has led to the determination of the electron mass [1], tests of the many-electron QED [2] as well as relativistic recoil [3] effects. Here, we summarize recent results in theoretical calculations of the bound-electron g factor of H-, Li-, and B-like ions. Moreover, we discuss possibilities for investigations of nuclear and nonlinear effects as well as fine structure constant determination from g factors of heavy ions.
