The Electron - Water Vapor (H2O) Collision Cross Sections

Abstract

Water vapor (H2O) is one of the minor constituents of the atmosphere and it plays an important role in the deionization processes of the partially ionized air. It controls the air conductivity, especially that of the the unheated air. Therefore, the role of H2O in modifying the electron velocity distribution in wet air is required for characterizations of partially ionized wet air. This requires the solution of a Boltzmann equation with an appropriate set of electron-molecule scattering cross sections. This report, accordingly, presents a set of up to date cross sections for the electron - H2O collisions over a wide range of electron energies. The set comprises the total, ionization, dissociative ionization, dissociative excitation, electronic, vibrational, rotational, elastic and momentum transfer cross sections.
