Mass spectrometric studies on free clusters composed of single fullerene molecules and transition metal atoms (C{sub 60}{ital M}{sub {ital x}} and C{sub 70}{ital M}{sub {ital x}}; {ital x}=0.150, {ital M}{element_of}{l_brace}Ti,V,Nb,Ta{r_brace}) reveal that they undergo a laser induced transformation from metal-fullerene clusters to metal carbide and metallo-carbohedrene clusters. Two types of fragmentation behavior are observed. Fullerenes doped with titanium or vanadium seem to be stable at low laser intensities, whereas tantalum and niobium severely destabilize the fullerene cage. Photofragmentation spectra of preselected C{sub 60}Ta{sub {ital x}} indicate that the C{sub 60} cage is destroyed for {ital x}{ge}3. {copyright} {ital 1996 The American Physical Society.}
