Free-electron model for the inelastic collision of fast electrons with benzene

Abstract

Using a free-electron wave function the cross section for the excitation of the first excited state and that for the ionization of benzene in the inelastic collision with fast electrons have been estimated. In the ionization process the cross section has been found to be maximum when the secondary electron moves away with a kinetic energy of about 3eV. For incident-electron energy above 20eV the cross section for ionization is larger than that for excitation, while below it the reverse is the case.
