Abstract

Multiply charged ion-induced fragmentation and ionization of C60 is governed by electronic and nuclear stopping of the projectile as well as charge exchange. We have studied the collision dynamics as a function of the projectile atomic number Z ( 2</=Z</=18) for constant projectile velocity v at charge states q = 2,3. Strong oscillations of electronic-stopping-related quantities such as ionization and fragmentation are observed. From the properties of the oscillations, we obtain information on the effective electron density of the fullerene.
