Measurement of Differential Cross Sections of Low-Energy Electrons Elastically Scattered by Gas Molecules. III. Effect of Intramolecular Double Scattering as Observed in the Scattering of 70–400 eV Electrons by Carbon Tetrachloride

The relative differential cross sections of electrons scattered by CCl 4 were measured by a cross-beam method at the incident energies of 70, 200 and 400 eV and at scattering angles between 4 and 135°. Calculations based on the independent-atom model including intramolecular double scattering and polarization accounted for the measured cross sections; they were used for normalization of the measured relative cross sections.
