High energy elastic and inelastic electron scattering by the NH3 molecule-binding effect

Abstract
From the measurement of high energy elastic and inelastic electron scattering by the NH3 molecule we find that molecular elastic scattering calculation agrees with experiment, but the independent atom model for molecular inelastic scattering does not reproduce the experiment, even when electron correlations are taken into account. This means that the inelastic scattering by molecules is strongly affected by the rearrangement of the charge densities during the bond formation.
