We have studied the formation and stability of pure and mixed clusters of C60 and C60/C70 produced in a gas aggregation source. The source yields very smooth abundance distributions indicating an efficient cooling. The stability of the clusters was probed by varying the degree of heating with a XeCl excimer laser (hν < I.P.) followed by single photon ionisation with a F2 excimer laser. The stability patterns show features related to geometrical packing structures but much stronger than previously seen in cluster spectra. The fragmentation patterns for the mixed clusters indicate that C60 and C70 have similar binding energies in the clusters in contrast to what would be expected from vapour pressure data of macroscopic samples.
