The current status of bound state quantum electrodynamics calculations of transition
energies for few-electron ions is reviewed. Evaluation of one and two body QED correction …

Recent progress in quantum electrodynamics (QED) calculations of highly charged ions is
reviewed. The theoretical predictions for the binding energies, the hyperfine splittings, and …

Within a systematic approach based on dimensionally regularized nonrelativistic quantum
electrodynamics, we derive a complete result for the two-loop correction to order (α∕ π) 2 (Z …

A method is proposed to determine the M 1 nuclear transition amplitude and hence the
lifetime of the “nuclear clock transition” between the low-lying (∼ 8 eV) first isomeric state …

The paper presents the current status of the theory of bound-electron g factor in highly
charged ions. The calculations of the relativistic, quantum electrodynamics (QED), nuclear …

We present a laser-microwave double-resonance technique for the precise determination of
g factors in heavy, highly charged ions confined in a Penning trap. This technique allows …

The shielding of the nuclear magnetic moment by the bound electron in hydrogenlike ions is
calculated ab initio with inclusion of relativistic, nuclear, and quantum electrodynamics …

We report an ab initio calculation of the shielding of the nuclear magnetic moment by the
bound electron in hydrogenlike ions. This investigation takes into account several effects …

The fully relativistic theory of the Zeeman splitting of the 1 s hyperfine-structure levels in
hydrogenlike ions is considered for the magnetic field magnitude in the range from 1 to 10 T …

Recent years have witnessed a remarkable improvement in the theoretical description of
bound-electron g factors, paralleled with a quantum jump in the experimental accuracy in …
