Z oscillations in ion-induced fullerene fragmentation

Multiply charged ion-induced fragmentation and ionization of C-60 is govern ed by electronic and nuclear stopping of the projectile as well as charge e xchange. We have studied the collision dynamics as a function of the projec tile atomic number Z (2 less than or equal to Z less than or equal to 18) f ur constant projectile velocity upsilon at charge states q = 2, 3. Strong o scillations of electronic-stopping-related quantities such as ionization an d fragmentation are observed. From the properties of the oscillations, we o btain information on the effective electron density of the fullerene.
