Abstract
Results are reported for the rotationally elastic, inelastic and summed cross sections (differential, integral, momentum transfer and energy loss)from electron-CH4 scattering in the 0.1-20 eV energy region. Electron exchange is treated exactly and distortion effects are included using the parameter-free model polarisation potential. Agreement with available experimental measurements is good The results are also compared with other theoretical treatments. The authors also report the value of the scattering length from the model.Keywords
