The g(j) factor of a bound electron and the hyperfine structure splitting in hydrogenlike ions [Review]

摘要

The comparison between theory and experiment of the hyperfine structure splitting and the electronic g(j) factor in heavy highly charged ions provides a unique testing ground for quantum electrodynamics in the presence of strong electric and magnetic fields. A theoretical evaluation is presented of all quantum electrodynamical contributions to the ground-state hfs splitting in hydrogenlike and lithiumlike atoms as well as to the g(j) factor. Binding and nuclear effects are discussed as well. A comparison with the available experimental data is performed, and a detailed discussion of theoretical sources of uncertainty is included which is mainly due to insufficiently known nuclear properties.
