Abstract
Stark-broadening parameters have been calculated for 114 spectral lines of triply charged lead ion (Pb IV) using semiclassical perturbation approach in the impact approximation. The provided widths and shifts have been obtained for a set of temperatures from 20 000 to 300 000 K and an electron density of 10(17) cm(-3). The studied lines correspond to transitions between the configurations 5d(10) nl-5d(10)n'l' and 5d(9)6s(2)-5d(10)nl. Energy levels and oscillator strengths needed for this calculation have been calculated using a Hartree-Fock relativistic (HFR) approach. Comparison has also been made with available theoretical and experimental results. In addition, the regularity in the 5d(10)6s(2)S(1/2)-5d(10)np(2)P(1/2)(o) spectral series has been studied.
