Charge transfer and Coulomb fragmentation in slow collisions of Xe25+ ions with Ar dimers

We have evaluated removal and charge transfer cross sections for Xe25+-Ar2 collisions at the impact velocity v = 0.3 a.u. The theoretical method includes the many-electron aspect of the problem and makes use of the classical molecular dynamics (CMD), which includes over-barrier (OB) and tunneling (TU) mechanisms. We have studied the Coulomb fragmentation of the dimer and showed the preference for asymmetric channels.
