Self-energy corrections to the ionization energies in sodium-like ions: comparison of the \textit{ab initio} QED and model-QED-operator approaches
P. Yang, A. V. Malyshev, E. A. Prokhorchuk +3
Calculations of the self-energy corrections to ionization energies of the , , and states in sodium-like ions with nuclear-charge numbers , , …
QED calculations of intra--shell doubly excited states in Be-like ions
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…
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…
QED calculations of intra--shell singly excited states in Be-like ions
A. V. Malyshev, Y. S. Kozhedub, V. M. Shabaev +1
The \textit{ab initio} approach is used to evaluate the excitation energies of the states from the ground state as well as the $2s2p \, ^3P_1 \rightarrow 2s2p…
