Abstract:
Level energies, wavelengths, electric dipole, magnetic dipole,
electric quadrupole, and magnetic quadrupole transition rates,
oscillator strengths, and line strengths from combined relativistic
configuration interaction and many-body perturbation (MBPT)
calculations are reported for the 201 fine-structure states of the
2s22p6, 2s22p53l, 2s2p63l, 2s22p54l, 2s2p64l,
2s22p55l, and 2s22p56l configurations in all Ne-like ions
between CrXV and KrXXVII. Calculated level energies and transition
data are compared with experiments from the National Institute of
Standards and Technology (NIST) and CHIANTI databases, and other
recent benchmark calculations. The mean energy difference with the
NIST experiments is only 0.05%. The present calculations significantly
increase the amount of accurate spectroscopic data for the n>3 states
in a number of Ne-like ions of astrophysical interest. A complete data
set should be helpful for analyzing new observations from solar and
other astrophysical sources, and is also likely to be useful for
modeling and diagnosing a variety of plasmas, including astronomical
and fusion plasma.
