    "abstract": "Accurate QED calculations of the interelectron interaction corrections for\nthe $(1s2p)2 {}^1 P_1$, $(1s2p)2 {}^3 P_1$ two-electron configurations for ions\nwith nuclear charge numbers $10\\le Z \\le 92$ are performed within the line\nprofile approach. Total energies of these configurations are evaluated.\nEmploying the fully relativistic treatment based on the {$j$--$j$} coupling\nscheme these energy levels become quasi-degenerate in the region $Z\\le 40$. To\ntreat such states within the framework of QED we utilize the line profile\napproach. The calculations are performed within the Coulomb gauge.",
