Title: Polarization effects on low-energy electron collisions with propane

Abstract: We employed the Schwinger multichannel method to compute elastic cross sections for low-energy electron collisions with propane (C(3)H(8)). The calculations are carried out within the static-exchange and static-exchange plus polarization approximations and covered the energy range from 0 to 15 eV. The computed differential cross sections show good agreement with the experiment, and the computed integral cross sections present the same shape as the measured total cross sections. We found a broad structure in the integral cross section around 8.5 eV and also a Ramsauer-Townsend minimum around 0.1 eV. These results are in agreement with the experimental observations.
