Fluorination effects in electron-scattering processes - comparative study

Systematic studies of electron interaction with perfluorinated targets carr ied out recently in our laboratory revealed a distinct increase of the tota l cross section, Q(tot), over the impact energy range from a dozen or so to several tens of electronvolts, A likely reason for this striking feature i s a significant contribution of elastic processes in this energy range. The ratio of the total ionization electron-scattering cross section to the tot al cross section can be expressed with a simple regression formula. That fo rmula was used to estimate the GeH4 ionization cross section. (C) 2001 Else vier Science Ltd. All rights reserved.
