Core-polarization effects, oscillator strengths and radiative lifetimes of levels in Pb iii
2009
Transition probabilities and oscillator strengths of 382 lines with astrophysical interest arising from 5d 9 6s 2 6p, 5d 10 6snl, 5d 10 6s 2 ,5 d 10 6p 2 ,5 d 10 6p7s and 5d 10 6p6d configurations and some levels radiative lifetimes of Pb III have been calculated. These values were obtained in intermediate coupling (IC) and using relativistic Hartree–Fock calculations including corepolarization effects. We use for the IC calculations the standard method of least-square fitting from experimental energy levels by means of Cowan computer code. The inclusion in these calculations of the 5d 10 6p7s and 5d 10 6p6d configurations has facilitated us a complete assignment of the levels of energy in the Pb III. Transition probabilities, oscillator strengths and radiative lifetimes obtained are generally in good agreement with the experimental
