Title Spectral properties of Sb IV from MCDHF calculations

English abstract
We report on extensive relativistic multiconfiguration Dirac–Hartree–Fock (MCDHF) spectrum calculations for Sb IV. Energies, LS-compositions and Landé gJ-factors for 60 odd- and even-parity states are computed along with lifetimes and rates for transitions between these states. Results for the 5s2 1S0–5s5p 3Po0 hyperfine-induced transition are also presented. Valence and core-valence electron correlation effects are accounted for by explicit configuration interaction. The calculated energies agree very well with experiment, but the labelling of some of the odd states is ambiguous due to close degeneracies between the 5p5d, 5s7p and 5p6s configurations. Computed lifetimes of the excited states are compared with values from cascade-corrected beam-foil measurements.
