J/A+A/365/656 Zr II & III electron-impact broadening parameters (Popovic+, 2001)

The electron-impact broadening effect in hot star atmospheres: The case of singly- and doubly-ionized zirconium. Popovic L.C., Milovanovic N., Dimitrijevic M.S. <Astron. Astrophys. 365, 656 (2001)> =2001A&A...365..656P
ADC_Keywords: Atomic physics Keywords: atomic data - plasma - stars: atmospheres Abstract: The electron-impact widths for 30 Zr III lines were calculated using the modified semi-empirical (MSE) method. For two Zr II and four Zr III astrophysically important UV lines, only electron-impact widths are given, since for their calculation the experimental oscillator strengths were used and consequently the accuracy of the parameters is lower than in the case of other lines. The influence of the electron-impact mechanism on line shapes and equivalent widths in hot star atmospheres was also considered. The impact of the electron-impact broadening effect on abundance determination, particularly its effect on "zirconium conflict" is discussed as well. File Summary:
