Title: Relaxation of selectively excited atoms at the surface of rare-gas doped rare-gas solids
Abstract: Abstract Following primary selective 3 P 1 type excitation of rare-gas guest atoms at the surface of rare-gas host crystals two relaxation channels are observed, (i) the desorption of electronically excited guest atoms, and (ii) the radiative decay of weakly bound atomic 3 P 1 and 3 P 2 type and of molecular-type surface centers. The desorption of excited atoms is ascribed to the ‘cavity-ejection mechanism’. The emitting atomic-type centers consist of guest atoms in an ‘on-top’ geometry. Measurements have been performed on all systems with positive V 0 values.
