摘要：

The first results of a Transmission Electron Microscopy study of Molybdenite (MoS2) irradiated with 20 MeV fullerene and 1 GeV lead ions are presented. It is shown that the energy deposited by electronic excitation by both types of projectiles leads to track formation. Although the value of the linear rate of energy deposition is comparable for 20 MeV C-60 clusters and 1 GeV Pb ions, the diameters of the tracks created by the clusters is two times greater than the diameter of the tracks induced by 1 GeV Pb ions. Furthermore, the tracks in the sample irradiated with fullerene ions present specific contrast features.
