Abstract
The cross section for ionization of the methane molecule by impact of fast electrons is evaluated by means of the Born approximation. Use is made of a single‐configurational wave function set up from analytic one‐center MO's for the description of the electronic ground state of the molecule. The wave function of the ejected electron resulting from ionization is approximated by a Coulomb continuum function. The calculated cross section is compared with experiment. The calculated momentum distribution of the ejected electron has a maximum at a very low momentum.Keywords
