Title: Electron-impact core excitation of SF{sub 6}. II. Generalized oscillator strengths in the S 2{ital p} region

Abstract

The generalized oscillator strengths (GOSs) for discrete and continuum S 2{ital p} excitations of SF{sub 6} have been derived in the momentum transfer range ({ital K}{sup 2}) of 1--20 a.u.{sup {minus}2} from the angular variation of the relative differential cross section for inelastic electron scattering. The experimental techniques and data processing procedures used to obtain reliable, absolute GOS values are documented. The GOS results are compared to recent literature results [J. F. Ying, C. P. Mathers, and K. T. Leung, Phys. Rev. A {bold 47}, R5 (1993)]. Some discrepancies are noted. These are found to arise largely, but not completely, from differences in the data analysis procedures used. The Bethe surface for SF{sub 6} in the region of S 2{ital p} excitation is derived and the important role of Compton scattering by valence electrons is illustrated.
