Abstract
Absolute differential, integral and momentum transfer cross sections for electron-methane collisions were determined using a crossed beam spectrometer for impact energies from 1.5-100 eV and angles from 10'-130'. Comparison with published total cross sections shows good agreement. At the shape resonance (7.5 eV) excitation measurements of the two vibrational peaks were taken and the angular distribution of their DCS was determined. The elastic DCS are compared with recent measurements and theoretical calculations.Keywords
