- Zr II fine structure analysis was newly achieved.
- Two semi-empirical approaches tested successfully recurring to comparison with experimental log gf data.
- Radial integral values of the main atomic transitions are given for the first time.
- Oscillator strength values are derived semi-empirically in a wide wavelength range: 1616-14,746Â Ã
.
In the present work, we compare the radiative transition rates computed by two different semi-empirical approaches, based on a parametrization of the oscillator strengths and on a pseudo-relativistic Hartree-Fock model including core-polarization effects, for spectral lines in singly ionized zirconium. A detailed comparison with available experimental results is also reported and an overall good agreement is observed between all sets of data allowing us to provide new reliable oscillator strengths for a large amount of Zr II lines in the wavelength region from 1616 to 14746Â Ã . Moreover, we give radial integral values of the main atomic transitions deduced in this study: ã4d25p|r1|4d25sã=â3.1522 (0.0161), ã4d25p|r1|4d3ã=1.7605 (0.0107), ã4d25p|r1|4d26sã=â1.481 (0.794) andã4d25p|r1|4d25dã=2.289 (0.014).
