Abstract
The differential, integrated elastic, total (elastic+inelastic), transport (momentum transfer and viscosity), and total ionization cross sections for electron and positron scattering from ethylene () molecule are calculated over the energy range of 1 eV−1 MeV. This report also provides the spin polarization data for the same scattering systems. Independent atom model (IAM) and the screening correction enclosed by the same model (IAMS) are used for the present work. Dirac partial wave analysis is used to compute the scattering observables, using a complex optical model potential (OMP). Comparison of our calculations with the experimental and theoretical results, available in the literature, has been made. This investigation shows the effectiveness of the IAMS, to describe the electron and positron scattering by .
