Experimental results of excimer laser-induced photolysis of fullerene C{sub 60} in solution are presented and are found in good agreement with recent ab-initio calculations, which confirm the relatively low energy demand for opening the fullerene carbon cages in their triplet excited states. Different quantum yields of photolysis show that a single photon of an ArF laser or two photons of KrF/XeCl lasers could be sufficient for opening the fullerene cage. The reaction of the opened C{sub 60} with solvent impurities or products of previous decompositions seems more likely than its oxidation by singlet oxygen or than multiphoton decomposition. 14 refs., 2 figs.
