Abstract
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 14746Å. Moreover, we give radial integral values of the main atomic transitions deduced in this study: 〈4d25p|r1|4d25s〉=−3.1522 (0.0161), 〈4d25p|r1|4d3〉=1.7605 (0.0107), 〈4d25p|r1|4d26s〉=−1.481 (0.794) and〈4d25p|r1|4d25d〉=2.289 (0.014).
