摘要：

Raman spectra of ultrathin C-60 films on SiOx (x approximate to 2) in ultra high vacuum show strong irradiation induced changes which persist but decay with time (2-3hours). The induced changes are suppressed upon cooling (120 K) and additional changes are introduced with heating (600 K). The observation of induced low energy vibrational bands between the molecular and lattice vibrational spectrum suggests the formation of covalent bonds between C-60 molecules. The short range intermolecular coupling has been estimated by applying the semi-empirical interatomic Tersoff potential.
