Query: Calculations with spectroscopic accuracy: energies and transition rates
  in the nitrogen isoelectronic sequence from Ar XII to Zn XXIV   Combined relativistic configuration interaction and many-body perturbation
calculations are performed for the 359 fine-structure levels of the $2s^2
2p^3$, $2s 2p^4$, $2p^5$, $2s^2 2p^2 3l$, $2s 2p^3 3l$, $2p^4 3l$, and $2s^2
2p^2 4l$ configurations in N-like ions from Ar XII to Zn XXIV. A complete and
consistent data set 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 serve identification and
interpretation of observed spectra involving the $n=3,4$ levels, for which the
experimental values are largely scarce. Meanwhile, the results should be of
great help in modeling and diagnosing astrophysical and fusion plasmas.
