- We report relativistic multiconfiguration Dirac–Hartree–Fock calculations of transitions between the hyperfine levels of 4s4f 3F2,3 and 4s4d 3D2 in Ga II. The capacity of two newly developed programs connected to the graspVU package for generating synthetic spectra is explored. The obtained theoretical spectra are compared to Fourier transform spectra and good agreement is found. The importance of hyperfine induced interference effects for the 4s4d 3D2–4s4f 3F2 transitions is pointed out, and the gf values for all the hyperfine transitions are given.

Tidskriftsartikel (refereegranskat)abstract
- We report relativistic multiconfiguration Dirac-Hartree-Fock calculations of oscillator strengths and hyperfine structures for a large number of electric dipole transitions in Ga II. Results for the 4s(2) S-1(0)-4s4p 3P(0)(o) hyperfine-induced transition are also given. Core polarization is accounted for by means of explicit CI. To describe spin and orbital polarization, which are important for the hyperfine structures, configuration state functions obtained by single excitations from all core shells are included in the expansions. The computed oscillator strengths for transitions between low-lying states are in good agreement with recent CIV3 calculations. The hyperfine interaction constants are in close agreement with experimental constants derived from Fourier transform spectra.
