Oxygen-like ions Energies and transition rates

Based on relativistic wave functions from multiconfiguration Dirac-Hartree-Fock and configuration interaction calculations, E1, M1, E2, M2 transition rates, weighted oscillator strengths, and lifetimes are evaluated for the states of the (1s^2^)2s^2^2p^4^,2s2p^5^, and 2p^6^ configurations in all oxygen-like ions between F II and Kr XXIX. Valence and core-valence correlation effects were accounted for through single-double multireference (SD-MR) expansions to increasing sets of active orbitals.

Computed energies are compared with the NIST recommended values, generally differing by less than 600cm^-1^.
