Low energy electron scattering from polyatomic targets

Abstract

Low energy elastic electron scattering cross-sections from water and several alcohols are presented. This paper addresses accurately measuring quantitative differential elastic scattering cross-sections, using the relative flow method with an aperture source, and focuses on the long range dipole interaction of the scattering electron with these polar targets. The electron-dipole interaction dominates the scattering for these molecules and contributes significantly to their integral elastic cross-sections.
