Coupled Channels Optical Method Study for Elastic Scattering Process of Electron--N₂ Collisions

Different cross sections for the elastic scattering of electrons by N₂ at impact energies of 10, 15, 20, 30, 40eV have been calculated and compared with the experimental data and other theoretical results. The present results are obtained by the momentum space coupled channels optical method. In this method, the e--molecule system has a single centre and the interaction of e--nuclei is expanded by a multipole expansion.
