Low energy electron-ethylene scattering

Elastic and inelastic cross sections for electron-ethylene scattering have been determined with the complex-Kohn method. The authors earlier elastic scattering studies of this system focused on the Ramsauer-Townsend minimum and the Π* shape resonance found in the total cross section. In this study they report the results of a more extensive set of elastic scattering calculations and also present electron impact excitation cross sections to the low-lying excited states. The mixed, valence-rydberg character of the V-state of ethylene makes the theoretical determination of the electron impact excitation cross section to this state particularly interesting and the authors will discuss the determination of the trial wave function needed to obtain this cross section
