QED corrections to the g factor of Li-like and B-like ions in a wide range of nuclear charges are presented. Many-electron contributions as well as radiative effects on the one-loop level are calculated. Contributions resulting from the interelectronic interaction, the self-energy effect, and most of the terms of the vacuumpolarization effect are evaluated to all orders in the nuclear coupling strength Zα. Uncertainties resulting from nuclear size effects, numerical computations, and uncalculated effects are discussed.

“…The uninterrupted developments of computational methodologies [1][2][3], together with the growing computational resources at the disposal of atomic physicists, have increased tremendously the accuracy of atomic structure calculations in the past decades [4][5][6][7][8][9][10][11]. Theoretical predictions of atomic properties have, therefore, become efficient tools to support the corresponding experimental measurements.…”

Ab initio electronic factors of the A and B hyperfine structure constants for the 5s25p6s<

Large-scale ab initio calculations of the electronic contribution to the electric quadrupole hyperfine constant B were performed for the 5s 2 5p6s 1,3 P o 1 excited states of neutral tin. To probe the sensitivity of B to different electron correlation effects, three sets of variational multiconfiguration Dirac-Hartree-Fock and relativistic configuration interaction calculations employing different strategies were carried out. In addition, a fourth set of calculations was based on the configuration interaction Dirac-Fock-Sturm theory. For the 5s 2 5p6s 1 P o 1 state, the final value of B/Q = 703(50) MHz/b differs by 0.4% from the one recently used by Yordanov et al. [Commun. Phys. 3, 107 (2020)] to extract the nuclear quadrupole moments Q for tin isotopes in the range 117−131 Sn from collinear laser spectroscopy measurements. Efforts were made to provide a realistic theoretical uncertainty for the final B/Q value of the 5s 2 5p6s 1 P o 1 state based on statistical principles and on correlation with the electronic contribution to the magnetic dipole hyperfine constant A.

“…Predictions can be improved with expansions that take into account the atomic property under investigation. Applications that have been extensively investigated are spectrum calculations for all levels up to a designated excited level, allowed and forbidden transitions [143,148,197,198,54], isotope shifts [199,200,201,184,202,203], hyperfine structures [204,159,205,206], nuclear effects on transition rates and spectra [26,207], magnetic field-induced transitions [208,209,20], to name a few. A comprehensive list of relativistic calculations and theoretical studies can be found in the RTAM bibliography database [210].…”

Abstract. Multiconfiguration wave function expansions combined with configuration interaction methods are a method of choice for complex atoms where atomic state functions are expanded in a basis of configuration state functions. Combined with a variational method such as the multiconfiguration Hartree-Fock (MCHF) or multiconfiguration Dirac-Hartree-Fock (MCDHF), the associated set of radial functions can be optimized for the levels of interest. The present review updates the variational MCHF theory to include MCDHF, describes the multireference single and double (MRSD) process for generating expansions and the systematic procedure of a computational scheme for monitoring convergence. It focuses on the calculations of energies and wave functions from which other atomic properties can be predicted such as transition rates, hyperfine structures and isotope shifts, for example.PACS numbers: 31. 31.15ag, 32.70.Cs
