“…Определение ядерного магнитного момента, в дополнение к прецизионным измерениям, требует точных теоретических предсказаний в рамках квантовой электродинамики (КЭД) для связанных состояний. Одновременно с экспериментом, релятивистская теория g-фактора связанного электрона получила значительное развитие в последние годы [13,14]. В ионах с ненулевым ядерным спином возникает поправка к g-фактору на сверхтонкое взаимодействие δg HFS .…”

The nuclear magnetic shielding is considered within the fully relativistic approach for the ground state of H-, Li-, and B-like ions in the range Z=32-92. The interelectronic interaction is evaluated to the first order of the perturbation theory in Li- and B-like ions. The calculations are based on the finite-field method. The numerical solution of the Dirac equation with the magnetic-field and hyperfine interactions included within the dual-kinetic-balance method is employed. The nuclear magnetic shielding constant is an important ingredient for accurate determination of the nuclear magnetic moments from the high-precision g-factor measurements.

“…The follow-up measurements in lithium-like [6][7][8] and boron-like [9][10][11] ions are evolving towards a comparable level of precision. Analyzing experimental data and corresponding results from elaborate theoretical calculations, one can determine fundamental constants and nuclear parameters [12][13][14]. In particular, the currently accepted value of the electron mass was obtained from the analysis of the g-factor measurements in 12 C 5+ and 28 Si 13+ ions and the corresponding theory [3,15,16].…”

The influence of the blackbody radiation field on the g-factor of light hydrogenlike ions is considered within the framework of quantum electrodynamics at finite temperature for bound states. One-loop thermal corrections are examined for a wide range of temperatures. The numerical results for 1s, 2s, 2p 1/2 , and 2p 3/2 states are presented. It is shown that for excited states finite temperature corrections to the bound-electron g-factor are close to the level of current experimental uncertainty even at room temperatures and can be discerned within the measurements anticipated in the near future.

“…Precision spectroscopy of one-and few-electron ions is a powerful tool for testing fundamental physical theories [1][2][3][4][5][6][7][8][9]. It has also allowed the most precise determination of the electron mass [10,11] at the time.…”

The influence of hypothetical new interactions beyond the Standard Model on atomic spectra has attracted recent interest. In the present work, interelectronic photon-exchange corrections and radiative quantum electrodynamic corrections to the hypothetical contribution to the energy levels of few-electron ions from a new interaction are calculated. The 1s, 2s and 2p 1/2 ground states of H-like, Li-like and B-like ions are considered, as motivated by proposals to use isotope shift spectroscopy of few-electron ions in order to set stringent constraints on hypothetical new interactions. It is shown that, for light Li-like and B-like ions, photon-exchange corrections are comparable to or even larger, by up to several orders of magnitude, than the leading one-electron contribution from the new interaction, when the latter is mediated by heavy bosons.
