The excitation of energetic atomic particles penetrating amorphous condensed matter

The emission of light from both the surface and the interior of a glass target bombarded by Ar + ions of energy 2.5–5keV was observed. The analysis of both kinds of radiation shows that excited Na atoms penetrating the glass undergo radiative relaxation. The relative number of Na atoms radiating ins...

Summary:The emission of light from both the surface and the interior of a glass target bombarded by Ar + ions of energy 2.5–5keV was observed. The analysis of both kinds of radiation shows that excited Na atoms penetrating the glass undergo radiative relaxation. The relative number of Na atoms radiating inside the glass increases with increasing energy of incident ions. It was stated that the radiation of Na atoms penetrating the glass is intensified when the near-surface layers become poor in sodium. However, no effect of radiative relaxation of Na atoms penetrating the condensed matter was found when the NaCl single crystal was bombarded by the same ion beam.
