A. V. Malyshev, Y. S. Kozhedub, V. M. Shabaev +1
The rigorous QED approach is employed to calculate the energies of the , , and states of selected Be-like highly charged ions over a w…
A relativistic coupled-cluster treatment of magnetic hyperfine structure of the and states of OH isotopologues
D. P. Usov, Y. S. Kozhedub, A. V. Stolyarov +3
calculations of the parallel component of the magnetic dipole hyperfine structure (HFS) constant have been carried out for hydroxyl radical isotopologues ($^{1…
Influence of the nuclear magnetic field on electron-positron pair production in low-energy heavy-nuclei collisions
N. K. Dulaev, D. A. Telnov, V. M. Shabaev +5
Total and energy-angle differential probabilities of positrons created in slow collisions of two identical nuclei are calculated within relativistic two-center approach. The time-d…
Ionization potential and electron affinity of superheavy element 119: relativistic high-order coupled cluster study with QED corrections
A. R. Saetgaraev, L. V. Skripnikov, I. I. Tupitsyn +5
We report a highly accurate \textit{ab initio} study of the ionization potential (IP) and electron affinity (EA) of element 119. Electronic correlation are treated within the relat…
