Absolute vibrationally elastic cross sections for electrons scattered from water molecules between 6 eV and 50 eV

Abstract

The authors report absolute vibrationally elastic differential cross sections for electrons scattered from water in the energy range 6-50 eV. From an extrapolation of the differential cross section data, absolute integral and momentum transfer cross sections have also been obtained. For incident electron energies above 20 eV and below 100 eV there exists only one previous report of differential cross sections (Danjo and Nishimura (1985)). Significant discrepancies have been found in this region between the cross sections reported by Danjo and Nishimura and those obtained in the present work.
