Abstract
Effective cross-sections σD(E) of fullerite C60 modification by electrons in the energy range E = 0.25–3000 eV were obtained using electron energy loss spectroscopy. Comparison of σD(E) with cross-section σF(E), describing fragmentation of individual fullerenes C60 in the gas state and known from literature, revealed several orders of magnitude difference between the absolute values of these cross-sections and the inverse behavior of their energy dependencies. This fact evidences that the mechanism of electron-induced destruction of fullerite C60 drastically differs from the one implied by the model of successive fragmentation of separate fullerenes and that condensed fullerenes C60 are radically more stable than it was considered earlier.
