Measurement of energy distributions of secondary electrons ejected from water vapor by fast electrons

Abstract

Energy distributions of the secondary electrons ejected from water vapor ionized by fast electrons have been measured. The energies of the primary electron beam ranged from 1 to 10 keV and ejected electron energies up to 300 eV were considered. Measurement of the secondary electron spectra has been made for electrons ejected over the total sphere and at angles of 30°, 60°, 90°, 120°, and 150° with respect to the primary electron beam.
