Abstract. A comparison of the adsorption efficiencies for Ar atoms on large (N2) m (m = 1320-10600) clusters and N2 molecules on large (Ar) n (n = 7900-17000) clusters has been investigated by the pick-up technique. Using mass spectroscopy, it has been shown that mixed (Ar) n (N2) m clusters can be created either by depositing Ar atoms from buffer gas on the surface of (N2) m clusters or by depositing N2 molecules from buffer gas on the surface of (Ar) n clusters. The composition of mixed (Ar) n (N2) m clusters has been determined as a function of cluster size and buffer gas pressure. The adsorption efficiency for Ar on (N2) m clusters is found to be significantly higher than that for N2 on (Ar) n clusters. This effect is attributed to the difference in Ar-Ar, N2-N2 and Ar-N2 binding energies.
