A 66, 042506, 1-12 (2002) | | Subject: | Atomic Physics | physics.atom-ph | | Abstract: | Energies of (2s2 2p5 3l3l’) and (2s 2p6 3l3l’) 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 lowest order. The Lamb shift correction to energies is also included in 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. | | Source: | arXiv, physics/0206062 | | Services: | Forum | Review | PDF | Favorites | |
