Interactction of microscopic alkalimetal clusters with insulating surface

Atom physics and physics of clusters and nanostructures

The results of theoretical study of processes that occur during the collision of neutral sodium cluster with insulating NaCl surface are presented. It was shown that the cluster capture into a bound state in vicinity of the substrate surface takes place only for initial kinetic energies below the energy threshold; a collision at the energies above the threshold is inelastic and is accompanied by irreversible cluster fragmentation.
