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 5d10 6s np (n= 6,7,8), 5d10 6s ns (n= 7,8,9) and 5d10 6s 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 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 ÷ Lupy and several subdwarf B and OB stars
