Popis: For the first time in the literature, the angular distribution of the double-differential cross section of a methane molecule is measured and calculated at 300 and 350 eV electron impact energies. Experiments were carried out with a conventional electron spectrometer. The theoretical results were obtained using the first Born approximation and the one-Coulomb wave model corrected by the Gamow factor to take into account the post-collision interaction between the outgoing electrons. The agreement between experiment and theory indicates that the one-Coulomb wave model is a reliable theoretical approach to describe electron–methane interactions.
