Absolute total cross sections for the scattering of low energy electrons by CCl4, CCl3F, CCl2F2, CClF3, and CF4

Absolute total electron scattering cross sections were measured with a time-of-flight electron transmission spectrometer for incident electron energies ranging from 0.6 to 50 eV. The halomethanes studied exhibit low energy structure which can be associated with electron capture processes. Comparisons are made with recent experiments and calculations.
