Elastic Scattering of Electrons from H2O Molecule

Abstract
Elastic differential cross sections (DCS's) for H 2 O have been measured in the energy range from 4 to 200 eV and in the angular range from 10° to 120° by a crossed beam method. The absolute scale of the DCS's was given by normalizing the relative values to the absolute elastic DCS's for He with the relative flow method. Integral and momentum transfer cross sections were derived from the DCS's and compared with the previous experimental and theoretical results.
