J/MNRAS/401/1080  Stark broadening of PbIV spectral lines (Alonso-Medina+, 2010)

Stark broadening of PbIV spectral lines of astrophysical interest. Alonso-Medina A., Colon C., Montero J.L., Nation L. <Mon. Not. R. Astron. Soc., 401, 1080-1090 (2010)> =2010MNRAS.401.1080A
ADC_Keywords: Atomic physics Keywords: atomic data - atomic processes 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. File Summary:
