The total cross sections of chlorofluoromethane molecules were measured in the 75--4000-eV range. A comparison is given with existing experimental and theoretical data. The present data and previous measurements in the 15--50-eV range were fitted with a Born-like formula. This simple fit allows the cross sections to be reproduced within experimental errors. Phenomenological double Yukawa scattering potentials can be derived from the formula. A short discussion for the total-cross-section partitioning is given for ${\mathrm{CF}}_{4}$, ${\mathrm{CF}}_{2}$${\mathrm{Cl}}_{2}$, and ${\mathrm{CCl}}_{4}$.read more

Screening corrections for calculation of electron scattering differential cross sections from polyatomic molecules
TL;DR: In this paper, an ab initio approximate procedure is obtained for the screening correction of molecular differential cross sections calculated in the independent atom approximation, and the resulting treatment is very simple and its application to CO2, CF4 and C3F8 sample molecules reveals significant improvements in the 10 −200 eV incident energy region.
