“…In particular, measurements of the g factor of H-like and Li-like calcium and silicon are currently in progress by the Mainz-GSI collaboration [5]. An extension of these studies to high-Z H-like, Li-like, and B-like systems planned in the framework of the HITRAP project [6,7] will provide a stringent test of the bound-state QED in the strong electric field of the nucleus. Moreover, investigations of the g factor of heavy B-like ions can lead to an independent determination of the fine structure constant [8].…”

The screened QED corrections of the first orders in α and 1/Z to the g factor and the hyperfine splitting of lithiumlike ions are evaluated within ab initio quantum electrodynamical approach. The complete gaugeinvariant set of the two-electron self-energy diagrams in the presence of the magnetic field and a dominant part of the two-electron vacuum-polarization diagrams are calculated. The most accurate values of the g factor of Li-like lead and uranium are presented. The theoretical prediction for the specific difference of the hyperfine splittings of H-and Li-like bismuth is improved.

Here we would like to mention a possibility for an independent determination of the fine structure constant α.…”

Quantum electrodynamics theory of heavy ions and atoms is considered. The current status of calculations of the binding energies, the hyperfine splitting and g factor values in heavy few-electron ions is reviewed. The theoretical predictions are compared with available experimental data. A special attention is focused on tests of quantum electrodynamics in strong electromagnetic fields and on determination of the fundamental constants. Recent progress in calculations of the parity nonconservation effects with heavy atoms and ions is also reported.

The accuracy of theoretical values for the g factor of high-Z H-like ions is presently limited by nuclear effects.…”

The current status of theoretical investigations of spectroscopic properties and fundamental interactions in highly charged ions is reviewed. Laying special attention on tests of quantum electrodynamics at strong fields recent progress in calculations of energy levels, hyperfine splitting and g factor values is reported. The parity nonconservation effect on the laser-induced 2 3 S 1 − 2 1 S 0 transition in heavy He-like ions is studied, which could serve as test scenario for the Standard Model in low-energy atomic physics. The Coulomb glory effect in collisions of antiprotons with heavy ions is considered. It is emphasized that observation of this effect in collisions of antiprotons with bare nuclei would exhibit the screening properties of the vacuum polarization potential. A new approach to the description of dynamic atomic processes in low-energy heavy-ion collisions is presented. As a first application of this approach, the charge transfer probabilities for the U 91+ (1s) -U 92+ collision are evaluated.
