Energy Spectra of Hydrogen Atoms Reflected from a Tungsten Surface

Abstract

Computer simulations were used to calculate the energy spectra and angular distributions of reflected particles during bombardment of the tungsten surface with hydrogen and deuterium atoms with energies of 0.1–10 keV. A model was proposed that qualitatively explained the main regularities in the behavior of the spectra. The similarity of the energy spectra upon bombardment by hydrogen and deuterium atoms at the same collision velocities has been established. The angular distribution of reflected particles was universal in a wide range of initial energies of the bombarding atoms.
