Abstract:
Employing two state-of-the-art methods, multiconfiguration
Dirac-Hartree-Fock and second-order many-body perturbation theory, the
excitation energies and lifetimes for the lowest 200 states of the
2s22p4, 2s2p5, 2p6, 2s22p33s, 2s22p33p, 2s22p33d,
2s2p43s, 2s2p43p, and 2s2p43d configurations, and multipole
(electric dipole (E1), magnetic dipole (M1), and electric quadrupole
(E2)) transition rates, line strengths, and oscillator strengths among
these states are calculated for each O-like ion, from CrXVII to
ZnXXIII. Our two data sets are compared with the National Institute of
Standards and Technology and CHIANTI compiled values, and previous
calculations. The data are accurate enough for identification and
deblending of new emission lines from the Sun and other astrophysical
sources. The amount of high-accuracy data is significantly increased
for the n=3 states of several O-like ions of astrophysical interest,
where experimental data are very scarce.
