|Title:||Low-energy elastic scattering of electrons by ethylene|
|Abstract:||Elastic differential, integral, and momentum-transfer cross sections are reported for electron scattering by C(2)H(4) at impact energies ranging from 1 to 50 eV. The Schwinger iterative variational method in the fixed-nuclei, static-exchange plus correlation-polarization approximation is used to calculate the scattering amplitudes. Integrated cross sections are also calculated below 1 eV, showing the existence of a Ramsauer-Townsend minimum in this region. Our calculated cross sections are compared with recent experimental data and other theoretical results.|
