Our previous model for dimer sputtering is extended to the formation of larger clusters. A simple analytical expression is obtained for the energy distribution of any cluster in the high energy limit. Comparison with experimental data on ionic tungsten clusters shows agreement. Indications are found that for the ionic crystal KI sputtering of non-adjacent K and I atoms from the lattice gives an important contribution to dimer formation.
