Abstract
Absolute elastic cross sections for e-C2F6 collisions have been measured for impact energies of 2 to 100 eV and scattering angles from 10 to 130 degrees . From these, the integrated and momentum transfer cross sections were obtained by extrapolation and numerical integration. Energy loss spectra were measured for vibrational excitation. The vibrational excitation functions show resonances at 4.3 eV and 8.5 eV. By decomposition of the loss spectra and symmetry analysis according to angular correlation theory, the resonances have been assigned to a temporary trapping of the electrons in the a2u (4.3 eV) and eu (8.5 eV) antibonding orbitals of the molecule.This publication has 33 references indexed in Scilit:
