摘要
Photo-stimulated desorption of ions from methane and water heteroclusters on the surface of solid neon was studied. The desorption yields of various photo-desorbed species showed strong dependence on the composition and size of the mother cluster. It was found that presence of a water molecule in the cluster significantly enhanced, or was almost essential for, desorption of all species observed. Systematic investigation of the correlation between the cluster size and desorption yield of each ion revealed the corresponding mother cluster for each species of the desorbed ions.
