cds-question@unistra.fratomic-physicsUsing 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 5d^10^ns (n=7,8), 5d^10^6p, 5d^9^6s6p, 5d^10^nd (n=6,7), 5d^10^5g and 5d^10^nh (n=6,7) configurations have been calculated in this way. Stark widths and shifts are presented for an electron density of 10^17^cm^-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 1313.1{AA} resonance line. Common trends for the Stark width of the resonance lines have been found and are discussed.2010MNRAS.401.1080Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/401/1080CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/401/1080https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/401/1080http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/401/1080https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/401/1080https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/401/1080http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/401/1080GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/401/1080/pb-ivStark broadening of PbIV (82.03)TransTransition arrayphys.atmol.transProb;phys.atmol.transitionrecnoRecord number assigned by the VizieR team.
