The production of the new carbon allotrope (C60) in macroscopic quantities has opened a completely new research field for physics, chemistry and material science. Since then the structural stability of C60 fullerene under ion irradiation has been attracting considerable attention. The solid fullerite has been irradiated with various ions in a wide range of energy from keV to MeV. Ion irradiation of C60 samples results in partial or total destruction of the C60 molecules and finally amorphization at certain irradiation doses depending on the nature and energy of the projectile. But the structural damage mechanism is not very clear up to now or is disputable because of the complexity of the kinetic procedure leading to the structural damage and of the lack of experimental data special for GeV energy ions.
