Abstract
We have investigated small-angle electron scattering by highly polar molecules. Recoil experiments are performed at 5 and 20 eV for electrons scattered by LiBr and CsCl, within the shadow of the unscattered molecular beam. Low-angular-range scattering described by the Born approximation for rotating dipoles, combined with different theories for intermediate- and high-angle scattering, are compared with our results. Evaluated total scattering cross sections as well as momentum-transfer and viscosity cross sections are given. A general two-dimensional analysis of the recoil experiment is presented.Keywords
