Abstract
The exciton-induced desorption of excited argon atoms is studied by us ing a luminescence VUV spectroscopy. The channels of the desorption as sociated with both the self-trapping of surface excitons and the self- trapping of bulk excitons in the crystal subsurface area are analyzed. It is shown that nonthermalized excitons have a dominant role in the processes of excitation energy transfer to the surface.
