Phys. Rev. A 66, 042506 (2002) [12 pages]Relativistic many-body calculations of energies for core-excited states in sodiumlike ionsReceived 17 June 2002; revised 5 August 2002; published 17 October 2002 Energies of 2s22p53l3l′ and 2s2p63l3l′ states for sodiumlike ions with Z=14–100 are evaluated to second order in relativistic many-body perturbation theory starting from a neonlike Dirac-Fock potential. Second-order Coulomb and Breit interactions are included. Correction for the frequency dependence of the Breit interaction is taken into account in the lowest order. The Lamb shift correction to energies is also included in the lowest order. Intrinsic particle-particle-hole contributions to energies are found to be 20–30 % of the sum of one- and two-body contributions. Comparisons are made with available experimental data. These calculations are presented as a theoretical benchmark for comparison with experiment and theory. © 2002 The American Physical Society URL:
