Abstract
Total cross sections for electron impact ionization are necessary quantitie s for numerical modeling of plasma chemistry and for quantitative mass-spec trometric gas analysis. Theoretical cross sections for SF, SF2, SF3, SF4, a nd SF5 are calculated by the recently developed binary-encounter-Bethe (BEB ) model. The BEB model combines a modified form of the Mott cross section a nd the Bethe cross section. The results are compared with experimental cros s sections for SF3 and SF5 free radicals. In view of the success of the BEB method for SF6 and many other molecules, it is expected that the results p resented here will provide reliable total ionization cross sections for SFx (x = 1-5).
