Electron Scattering by Molecules with and without Vibrational Excitation. V. Elastic Scattering and Nonresonant Vibrational Excitation of N2 at 30–83 eV

Abstract

Model polarized Born approximation calculations are compared to all the available intermediate energy differential cross section data for elastic scattering by N₂ and for electron impact excitation of vibration in N₂. The various models predict the angle dependence of the elastic scattering differential cross sections accurately for scattering angles less than 40°–70° at 30 and 83 eV. Vibrational excitation is found to be dominated by the polarization interaction at 33–50 eV.
