Title: Relativistic CI calculations of spectroscopic data for the 2p{sup 6} and 2p{sup 5}3l configurations in Ne-like ions between Mg III and Kr XXVII

Energies, E1, M1, E2, M2 transition rates, oscillator strengths, and lifetimes from relativistic configuration interaction calculations are reported for the states of the 2p{sup 6}, 2p{sup 5}3s, 2p{sup 5}3p, and 2p{sup 5}3d, configurations in all Ne-like ions between Mg III and Kr XXVII. Core–valence and core–core correlation effects are accounted for through single and double excitations to increasing sets of active orbitals. The Breit interaction and leading quantum electrodynamic effects are included as perturbations. The results are compared with experiments and other recent benchmark calculations. In Mg III, Al IV, Si V, P VI, S VII, and Ar IX, for which experimental energies are known to high accuracy, the mean error in the calculated energies is only 0.011%.
