Fragmentation of small van der Waals clusters in slow collisions with highly charged ions

We have studied the fragmentation of small argon clusters in slow collisions with highly charged projectiles. The studied systems are Xeq+-ArN (N = 3, 5, 7, 10) for two impact velocities; v = 0.3 a.u. (for q=25) and v = 0.14 a.u. (for q = 5) which correspond to the impact energies 300 keV and 65 keV respectively. The theoretical method is based on the Classical Molecular Dynamics (CMD) which includes the Over-Barrier (OB) and tunneling (TU) mechanisms.
