The mass spectra and unimolecular fragmentation of the C-n(-) and CsmC
n- clusters sputtered from fullerite and graphite by Cs+ ions have bee
n investigated. The obtained results have shown that a drastic differe
nce between the sputtering of the fullerene substance and graphite was
not observed provided that the region of collision cascade is limited
by the carbon volume only. The possible mechanisms of cluster emissio
n have been discussed. Copyright (C) 1996 Elsevier Science Ltd.
