State-to-state cross sections for elastic and inelastic electron scattering by N2 at 20–35 eV, including resonant enhancement of vibrational excitation

We have calculated integral and differential cross sections for elastic scattering and rotational, vibrational, and rotational-vibrational excitation at 20, 25, and 30 eV. We have also calculated partial cross sections and eigenphase sums at these energies and at 35 eV. We present a detailed study of the resonance enchancement of the vibrational excitation cross section in this energy region.
