Complete two-loop correction to the bound-electron g factor
Krzysztof Pachucki, Andrzej Czarnecki, Ulrich D. Jentschura +1
Within a systematic approach based on the dimensionally regularized nonrelativistic quantum electrodynamics, we derive the complete result for the two-loop correction to order $(α/…
Hyperfine splitting in heavy ions with the nuclear magnetization distribution determined from experiments on muonic atoms
A. A. Elizarov, V. M. Shabaev, N. S. Oreshkina +1
The hyperfine splitting in hydrogenlike Bi, Tl, and Tl is calculated with the nuclear magnetization determined from experimental data on the hyperfine split…
Collisional and thermal ionization of sodium Rydberg atoms I. Experiment for nS and nD atoms with n=8-20
I. I. Ryabtsev, D. B. Tretyakov, I. I. Beterov +3
Collisional and thermal ionization of sodium nS and nD Rydberg atoms with n=8-20 has been studied. The experiments were performed using a two-step pulsed laser excitation in an eff…
Interelectronic-interaction effect on the transition probability in high-Z He-like ions
Paul Indelicato, V. M. Shabaev, A. V. Volotka
The interelectronic-interaction effect on the transition probabilities in high-Z He-like ions is investigated within a systematic quantum electrodynamic approach. The calculation f…
Relativistic and QED corrections to the g factor of Li-like ions
D. A. Glazov, V. M. Shabaev, I. I. Tupitsyn +4
Calculations of various corrections to the g factor of Li-like ions are presented, which result in a significant improvement of the theoretical accuracy in the region Z = 6-92. The…
Evaluation of the self-energy correction to the g-factor of S states in H-like ions
Paul Indelicato, V. A. Yerokhin, V. Shabaev
A detailed description of the numerical procedure is presented for the evaluation of the one-loop self-energy correction to the -factor of an electron in the and state…
