Semiempirical e-N2 elastic scattering cross sections from 5 eV to 1 keV

Abstract
Elastic scattering of electrons from molecular nitrogen has been represented by empirical analytic forms in many calculations of the spatial aspects of electron energy deposition. In this work, elastic scattering of electrons from molecular nitrogen is discussed in terms of phenomenological independent particle potential models which have a few adjustable parameters. Numerical computations are performed for a spheroidal and a spherical potential. By suitable adjustment of the potential parameters, both models accurately reproduce the experimental differential cross sections for incident electron energies in the range 5 eV to 1 keV. The potential parameters are found to be strongly energy-dependent at low energies, and to saturate at higher energies. The integrated cross sections are in reasonable agreement with experiment.
