Abstract:
Combined relativistic configuration interaction and many-body
perturbation calculations are performed for the 359 fine-structure
levels of the 2s22p3, 2s2p4, 2p5, 2s22p23l, 2s2p33l,
2p43l, and 2s22p24l configurations in N-like ions from Ar XII to
Zn XXIV. Complete and consistent data sets of energies, wavelengths,
radiative rates, oscillator strengths, and line strengths for all
possible electric dipole, magnetic dipole, electric quadrupole, and
magnetic quadrupole transitions among the 359 levels are given for
each ion. The present work significantly increases the amount of
accurate data for ions in the nitrogen-like sequence, and the accuracy
of the energy levels is high enough to enable the identification and
interpretation of observed spectra involving the n=3, 4 levels, for
which experimental values are largely scarce. Meanwhile, the results
should be of great help for modeling and diagnosing astrophysical and
fusion plasmas.
