Elastic electron scattering from CH₄ for collision energies between 0.2 and 5 eV

Angular dependences of the elastic scattering of electrons from CH₄ for impact energies between 0.2 and 5 eV in the angular range between 15 degrees and 138 degrees are presented. Absolute differential cross sections have been obtained. With the help of a phaseshift analysis, integrated cross sections are calculated. The Ramsauer minimum is found to be at a collision energy close to 0.45 eV. The sum of the integrated vibrationally elastic cross sections and the vibrational excitation cross sections yields the total cross sections. These data are compared with the recent data for sigma _T of Ferch et al. (1985).
