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 5d 10 6s n p ( n = 6,7,8), 5d 10 6s n s ( n = 7,8,9) and 5d 10 6s n d ( 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 10 17 cm −3 . 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.
