N2 - Accurate QED calculations of the interelectron interaction corrections for the (1s2p)2(1)P(1) and (1s2p)2(3)P(1) two-electron configurations for ions with nuclear charge numbers 10less than or equal toZless than or equal to92 are performed within the line profile approach. Total energies of these configurations are evaluated. Employing the fully relativistic treatment based on the j-j coupling scheme these energy levels become quasidegenerate in the region Zless than or equal to40. To treat such states within the framework of QED we utilize the line profile approach. The calculations are performed within the Coulomb gauge.
