QED calculations of intra- $L$ -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 $2 p 2 p^{3} P_{0, 1, 2}$ , $2 p 2 p^{1} D_{2}$ , and $2 p 2 p^{1} S_{0}$ states of selected Be-like highly charged ions over a w…

QED calculations of intra- $L$ -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 $2 s 2 p^{2 S + 1} P_{J}$ states from the ground state as well as the $2s2p \, ^3P_1 \rightarrow 2s2p…
