The Binary-Encounter-Bethe(BEB) model, proposed by Kim and Rudd, in 1994,
was recently extended by Coimbra & Barbieri to obtain doubly differential
cross section (DDCS) for the scattering of electrons by atoms and
molecules. DDCS results are presented in comparison to experimental
results and the agreement is quite good.
