Role of the intramolecular multiple scattering on electron diffraction from nitrogen molecule in the intermediate energy range

Abstract

We report a systematic study on the role played by the intramolecular multiple scattering on elastic electron-nitrogen molecular collisions in the 50eV–1keV energy range. In our study, the elastic differential cross-sections are calculated using two theoretical approaches: the independent atom model and the overlap atom model. The Schwinger variational iterative method is used in the OAM calculations. Our study reveals that even for a simple diatomic molecule, such as N2, the contribution of the intramolecular multiple scattering effect is very important for incident energies E0≤300eV. However, the influence of this effect decreases rapidly with increasing incident energies.
