Elastic and inelastic e-CF₄cross sections at low energies: fit to the experimental data

Abstract

The momentum transfer elastic and the total vibrationally inelastic electron-CF4 cross sections at energies 0.02-4 eV are varied until the best fits of the measured electron drift velocity and diffusion/mobility ratio are obtained. The elastic cross section exhibits a well pronounced minimum somewhere in the range 0.2-1.3 eV.
