Extended Calculations with Spectroscopic Accuracy: Energy Levels and Transition Properties for the Fluorinelike Isoelectronic Sequence with Z = 2430
Abstract
We have performed extensive multiconfiguration DiracHartreeFock calculations and secondorder manybody perturbation calculations for Flike ions with Z = 2430. Energy levels and transition rates for electric dipole (E1), electricquadrupole (E2), electricoctupole (E3), magnetic dipole (M1), and magneticquadrupole (M2) transitions, as well as radiative lifetimes, are provided for the lowest 200 levels belonging to the 1{s}^{2}2{s}^{2}2{p}^{5}, 1{s}^{2}2s2{p}^{6}, 1{s}^{2}2{s}^{2}2{p}^{4}3l, 1{s}^{2}2s2{p}^{5}3l, 1{s}^{2}2{p}^{6}3l, and 1{s}^{2}2{s}^{2}2{p}^{4}4l configurations of each ion. The results from the two sets of calculations are in excellent agreement. Extensive comparisons are also made with other theoretical results and observed data from the CHIANTI and NIST databases. The present energies and wavelengths are believed to be accurate enough to aid line identifications involving the n = 3 and n = 4 configurations, for which observations are largely missing. The calculated wavelengths and transition data will be useful in the modeling and diagnostics of astrophysical and fusion plasmas.
