Spectral properties of InII from MCDHF calculations

Abstract
We report extensive relativistic multiconfiguration Dirac-Hartree-Fock calculations of oscillator strengths and hyperfine structures for a large number of electric dipole transitions in In II. Results for the 5s(21)S(0)-5s5p P-3(0)o hyperfine induced transition are also presented. Core polarization is accounted for by means of explicit CI. To describe spin-polarization effects configuration state functions obtained by single excitations from all core-shells are included in the expansions. The computed oscillator strength for the 5s(2 1)S(0)-5s5p P-3(1)o intercombination transition is in good agreement with laser spectroscopy measurements of In+ ions in a radio-frequency trap. The calculated magnetic dipole hyperfine interaction constants... (More)

The computed oscillator strength for the 5s(2 1)S(0)-5s5p P-3(1)o intercombination transition is in good agreement with laser spectroscopy measurements of In+ ions in a radio-frequency trap. The calculated magnetic dipole hyperfine interaction constants agree very well with experimental constants derived from Fourier transform spectra. The problem with off-diagonal interactions affecting the hyperfine structures in closely spaced finestructure levels is discussed. (Less)
