Atomic structure, radiative lifetime and oscillator strength calculations in doubly ionized molybdenum (Mo iii)

Abstract

Radiative lifetimes, transition probabilities and oscillator strengths in doubly ionized molybdenum (Mo iii) are reported for the first time in the present paper. This new set of atomic data has been obtained by using a semi-empirical computational technique based on the pseudo-relativistic Hartree–Fock approach in which a large amount of intravalence and core–valence electron correlations were included. In view of the lack of theoretical and experimental data available in the literature for this ion, the reliability of the results obtained in our work is discussed on the basis of comparisons with the isoelectronic ion Nb ii for which an investigation was recently performed using a similar method (Nilsson et al 2010 Astron. Astrophys. 511 A16).
