Low-energy electron scattering by C2HF5

We report elastic and electronically inelastic cross sections for low-energ y electron scattering by pentafluoroethane, C2HF5. Our calculations were pe rformed using the Schwinger multichannel method. For elastic scattering, we calculated integral, differential, and momentum transfer cross sections fo r energies from 5 to 50 eV. In the inelastic case, we obtained integral and differential cross sections for electron-impact excitation of the 1 (1,3)A ' and 2 (1,3)A' excited states at the three-channel level of approximation. At higher energies, the elastic differential cross sections are quite simi lar to existing theoretical results for C2F6. Limited electronic-structure calculations were carried out to explore the dissociation behavior of the e xcited states. (C) 2001 American Institute of Physics.
