Abstract

We report cross sections for electronically elastic electron scattering by CF_4 from 1 to 40 eV, calculated within the static‐exchange approximation using the Schwinger multichannel method. Although the static‐exchange approximation does not give results that are accurate in detail below 20 eV, it is useful in understanding resonant features in the elastic and vibrationally inelastic cross sections. Above 20 eV, where the static‐exchange approximation is more reliable, we derive a dissociation cross section in fair agreement with experiment by subtracting our result from the measured total cross section. We compare our integral and differential cross sections with the results of recent elastic and vibrationally inelastic scattering experiments.
