Annotatsiya
Exciton-stimulated desorption of excited argon atoms is studied by using luminescence VUV spectroscopy. The channels of desorption associated with self-trapping of surface excitons and self-trapping of bulk excitons in the surface region of the crystal are analyzed. It is shown that the nonthermalized excitons play the major role in the transport of excitation energy to the surface.
