Relativistic configuration-interaction calculation of energy levels of core-excited states in lithium-like ions: argon through krypton

Abstract

Large-scale relativistic configuration-interaction calculation of energy levels of core-excited states of lithium-like ions is presented. Quantum electrodynamic, nuclear recoil, and frequency-dependent Breit corrections are included in the calculation. The approach is consistently applied for calculating all $n=2$ core-excited states for all lithium-like ions starting from argon ($Z=18$) and ending with krypton ($Z=36$). The results obtained are supplemented with systematical estimations of calculation errors and omitted effects.
