Abstract:
Using a semi-empirical approach, we report in this paper calculated
values of the Stark broadening parameters for 58 lines of PbIV.
They were calculated using a set of wavefunctions obtained from
Hartree-Fock relativistic calculations including core polarization
effects. Stark widths for 58 lines of PbIV arising from 5d10ns
(n=7,8), 5d106p, 5d96s6p, 5d10nd (n=6,7), 5d105g and 5d10nh
(n=6,7) configurations have been calculated in this way. Stark widths
and shifts are presented for an electron density of 1017cm-3 and
temperatures T=11000-200000K. These atomic data are relevant to the
analysis of PbIV detected in Far Ultraviolet Spectroscopic Explorer
spectra of hot subdwarf B stars and are used to determine the lead
abundance of the early B main-sequence star AV 304 in the Small
Magallanic Cloud by measuring the 1313.1Å resonance line. Common
trends for the Stark width of the resonance lines have been found and
are discussed.
