Abstract: | Transition probabilities and oscillator strengths of 382 lines with astrophysical interest arising from 5d96s26p, 5d106s n l, 5d106s2, 5d106p2, 5d106p7s and 5d106p6d 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 core-polarization 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 5d106p7s and 5d106p6d 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 data. |
