Abstract
We have calculated cross sections for vibrationally–electronically elastic electron−N2 scattering at 50 eV impact energy. The model interaction potential includes static, exchange, and polarization interactions calculated by the INDOX/1s method and the semiclassical exchange approximation with adiabatic polarization at large electron–molecule distances. The scattering is treated by converged rotational close coupling using a new channel decoupling scheme.
