Abstract

Semiclassical approximate values of the Stark parameters for several lines of Pb III are reported in this paper. The parameters were calculated using a set of wavefunctions obtained from Hartree–Fock relativistic calculations. Stark widths for 122 lines of Pb III arising from 5d¹⁰6s np (n=6,7,8), 5d¹⁰6s ns (n=7,8,9) and 5d¹⁰6s nd (n = 6,7) configurations have been calculated in this way. Stark widths and shifts are presented as a function of temperature for an electron density of 10¹⁷ cmˉ³. Our results are compared with available experimental data. These atomic data are relevant to the analysis of isotopic abundances of Pb III found in the atmospheres of the star χ Lupy and several subdwarf B and OB stars.
