Electron-molecule interactions. III. A pseudo-potential method for e--N2scattering

Abstract

For Pt. II see Abstr. A43069 of 1970. The low energy scattering of electrons by molecular nitrogen is calculated using a pseudo-potential method. Expressions for the cross sections in terms of the calculated S matrix elements are developed and momentum transfer cross sections are obtained which are in good agreement with experiment. The theory is then extended to predict rotational excitation cross sections and differential cross sections. It is suggested that this approach may enable electron molecule collision cross sections involving complex molecules to be calculated.
