Experimental results of excimer laser-induced photolysis of fullerene C-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-60 With solvent impurities or products of previous decompositions seems more likely than its oxidation by singlet oxygen or than multiphoton decomposition.
