Abstract : Simple group theoretical principles are applied to the consideration of electron scattering off atoms and diatomic and polyatomic molecules. For all scattering angles S(g)-S(u) is forbidden for atoms. This approach is also used to estimate relative strengths of electron-impact-induced transitions of diatomic and polyatomic molecules.
