Photofragmentation investigations were performed by using chromatograp
hically isolated pure samples of higher fullerenes and metallofulleren
es. Quite similar distributions of fragments were commonly observed fo
r five different fullerenes, and this fact supports the presence of a
''scrambled-cage'' structure in a highly excited fullerene cage. An en
hancement of the C-60 and C-70 signals was also observed as a result o
f ''delayed C-2-loss'' fragmentation within a time scale of about 60 m
u s after photoexcitation. Photodissociation study of mono- and di-met
allofullerenes revealed the qualitative difference in the fragment dis
tributions between them, suggesting that LaC82 would possess an endohe
dral, and Sc2C84 an exohedral, form.
