Abstract
In this paper the dependence of the binding energy per atom on the clu ster size for metal clusters supported on metal substrates is studied. A semi-empirical Anderson-Newns-Grimley model is applied to calculate qualitatively the binding energy for neutral adatoms. The influence o f the support on the ''even-odd'' oscillations is revealed and the com petition between the adatom-adatom and the adatom-substrate interactio n is discussed. The connection of the obtained results with some exper imental measurements is shown.
