We carry out a systematic study of Pb III properties using a hybrid method that combines configuration interaction and linearized coupled-cluster approaches. The calculations start from a [Xe]4f 14 5d 10 Dirac-Fock potential. Excitation energies and lifetimes of the 6p 2 , 6sns, 6snp, and 6snd (n ≤ 9) states are evaluated. Reduced matrix elements, oscillator strengths, and transition rates are determined for allowed electric-dipole transitions including these states. Extensive comparison with
