Abstract

The electron-beam-induced damage in a zeolite under 60-200 keV energy beam irradiation has both radiolitic and knock-on components and can be described by linear superposition of these two processes. Theoretical predictions supported by experiments at 60 keV suggest that for electron beam energies smaller than 70 keV, the damage to the specimen follows a radiolitic path. For energies larger than 200 keV, knock-on based sputtering of the material will dominate, while considerable radiolitic movement of the atoms will still be present.
