“…In Refs. [16,[26][27][28][29][30], the screened QED corrections were evaluated by introducing an effective local screening potential in the zeroth-order (Dirac) equation. However, the screening potential approximation does not provide a reliable estimation of the uncertainty.…”

The rigorous calculation of the vacuum-polarization screening corrections to the hyperfine splitting in Li-like bismuth is presented. The two-electron diagrams with electric and magnetic vacuum-polarization loops are evaluated to all orders in αZ, including the Wichmann-Kroll contributions. This improves the accuracy of the theoretical prediction for the specific difference of the hyperfine splitting values of H-and Li-like bismuth.

“…In particular, a rigorous evaluation of the screened QED corrections is needed. Approximate treatments of this effect were accomplished in [40][41][42][43][44] (see also references therein) by employing an effective screening potential in calculations of the one-loop self-energy and vacuum-polarization diagrams. The two-electron self-energy diagrams ( Fig.…”

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.

“…Approximate treatments of these corrections were considered in Refs. [36,37] (see also references therein), where an effective screening potential was used in calculations of the oneelectron self-energy and vacuum-polarization diagrams. The rigorous evaluations of the two-electron self-energy diagrams (Fig.…”

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.
