Low-energy elastic electron scattering form chloroethane, C2H5Cl

We report theoretical as well as (normalized) experimental differential and integral cross sections for vibrationally elastic scattering of low-energy electrons from chloroethane, C_2H_5Cl, also known as ethyl chloride. The theoretical cross sections were computed using the Schwinger multichannel variational method in the single-channel approximation, with polarization effects included via virtual excitations. Cross section measurements were made at incident energies ranging from 1 to 30 eV and at scattering angles from 10° to 125°. We compare our data to previous results for C_2H_5Cl and for the related molecule chloromethane.
