Measurements of branching fractions and hyperfine structure constants in singly ionized niobium (Nb II)

Summary, in English

The extensive analysis of Nb II by Ryabtsev et al. (2000) has made it possible for us to measure branching fractions (BFs) in Nb II. The BFs have been measured from spectral line intensities, recorded with the Lund UV Fourier transform spectrometer in the wavelength region 2500 to 5000
