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