We have performed accurate calculations of the hyperfine structure of the 2^{3}P state in the ^{9}Be atom with the help of highly optimized, explicitly correlated functions, accounting for the leading finite nuclear mass, radiative, nuclear structure

We perform highly accurate calculations of the leading order QED correction to the ground electronic state of molecular hydrogen. Numerical results are obtained for a grid of the internuclear distances $R=0-10$ au with the relative precision of about

The derivation of leading quantum electrodynamic corrections to the nuclear magnetic shielding in light hydrogen- and helium-like atomic systems is described in detail. The presented theoretical approach applies to any light atomic and molecular syst

The leading quantum electrodynamic corrections to the nuclear magnetic shielding in one- and two-electron atomic systems are obtained in a complete form, and the shielding constants of ^{1}H, ^{3}He^{+}, and ^{3}He are calculated to be 17.735 436(3)

The authors determine the deformation of the beryllium-9 nucleus in terms of the quadrupole moment using from the hyperfine splitting of the atomic triplet 2P state.
We perform accurate calculations of energy levels as well as fine and hyperfine splittings of the lowest $^{1,3}\!P_J$, $^{3}\!S_1$, $^{3}\!P^e_J$, and $^{1,3}\!D_J$ excited states of the $^9$Be atom using explicitly correlated Gaussian functions and

We perform the four-body calculation of the hyperfine structure in the first rotational state $J=1$ of the ${\mathrm{H}}_{2}$, ${\mathrm{D}}_{2}$, and HD molecules and determine the accurate value for the deuteron electric quadrupole moment ${Q}_{d}=

Large-scale ab initio QED calculations are performed for the $2{p}_{3/2}\text{--}2{p}_{1/2}$ fine-structure interval of Li-like ions with nuclear charges $Z=5\text{--}92$. Improved theoretical predictions are obtained by combining together two comple
