Screened QED corrections to the g factor of Li-like ions

Screened QED corrections to the g factor of Li-like ions

The screened QED corrections to the g factor of Li-like ions are evaluated utilizing an effective potential approach. The evaluation is performed within the range of nuclear charge numbers Z = 32 – 92. The results obtained serve for improving the theoretical predictions for the g factor of heavy Li-like ions. PACS numbers: 12.20.Ds, 31.30.Jv, 31.30.Gs

Hyperfine structure and g factor in heavy Li-like ions: rigorous evaluation of the screened QED corrections

Investigations of the hyperfine splitting and the g factor in highly charged ions give an access to a test of boundstate QED in strongest electromagnetic fields available at present for experimental study. To date, accurate measurements of the ground-state hyperfine structure and of the g factor were performed in H-like ions. An extention of such kind of experiments to highly charged Li-like io...

Relativistic and QED effects to the g factor of Li-like ions

New perspectives for testing QED effects via g factor of highly charged ions motivated numerous investigations on this subject during the last years. High-precision measurements of the g factor of light H-like ions [1, 2] provided a new determination of the electron mass to an accuracy which is four times better than that of the previously accepted value (see Ref. [3] and references therein). T...
