Track evolution in Y3Fe5O12 is analyzed in the range 0.02 MeV/nucleon<E<30 MeV/nucleon. By applying the phenomenological thermal spike model the track sizes in cluster beam experiments can be predicted within experimental error from studies with monoatomic ion beams. It is concluded that the various energy density parameters are not useful in the description of the track evolution in the full range of track sizes. A quantitative analysis indicates that the Waligorski distribution of δ-electron dose is not directly related to the velocity effect. The contributions of the electron-lattice ion and the ion-ion interactions to the energy transfer are discussed.
