“…The relative cross sections associated to the different elementary processes (ionization, excitation and electron capture from the atomic target) depend strongly on the collision regime, given by the comparison of the projectile velocity (v p ) to the orbital velocity of active electrons (v e ) and by the collision asymmetry, i.e. the ratio between the projectile and target atomic numbers [5][6][7][8]. It is today well established that, as ionization and excitation of the target dominates in the high velocity regime, charge exchange (or electron capture) is by far the most probable process at low energy.…”

We present a combined theoretical and experimental study of primary and post-collision mechanisms involved when colliding low energy multiply charged ions with van der Waals dimers. The collision dynamics is investigated using a classical calculation based on the Coulombic Over-the-Barrier Model adapted to rare-gas dimer targets. Despite its simplicity, the model predictions are found in very good agreement with experimental results obtained using COLd Target Recoil Ion Momentum Spectroscopy (COLTRIMS), both for the relative yields of the different relaxation processes and for the associated transverse momentum exchange distributions between the projectile and the target. This agreement shows to which extent van der Waals dimers can be assimilated to independent atoms. Way-In:Determination of the number of electrons shared between the projectile and the target. Way-Out:Determination of the number of electrons captured
