    "abstract": "Energies of (2s2 2p5 3l3l\u0027) and (2s 2p6 3l3l\u0027) states for sodiumlike ions\nwith Z =14--100 are evaluated to second order in relativistic many-body\nperturbation theory starting from a neonlike Dirac-Fock potential. Second-order\nCoulomb and Breit interactions are included. Correction for the\nfrequency-dependence of the Breit interaction is taken into account in lowest\norder. The Lamb shift correction to energies is also included in lowest order.\nIntrinsic particle-particle-hole contributions to energies are found to be\n20-30% of the sum of one- and two-body contributions. Comparisons are made with\navailable experimental data. These calculations are presented as a theoretical\nbenchmark for comparison with experiment and theory.",
