|Title:||Elastic Electron Scattering At Acetylene At Low And Intermediate Energies|
|Abstract:||We report calculated differential and integral cross sections for e-C 2H 2 collisions in the 10-200 eV energy range. These cross sections were derived from fixed-nuclei scattering amplitudes in such a way that the low angular momentum components are obtained using the Schwinger iterative method and the large ones are treated by a Born closure. Using this combined theory, it can be shown that the elastic differential cross sections obtained at the static-exchange level are nearly exact, even at higher energies. The inclusion of a semi-empirical polarization potential is discussed as well. © 1990 IOP Publishing Ltd.|
