Abstract

We report cross-section measurements of collisions between bare Ne¹⁰⁺ ions and C₆₀ at two different collision velocities (v=0.3 and 0.64 a.u.). We focus our attention on small impact parameter collisions ( radius), in which C₆₀ can be considered as a nanometric solid target. The final charge state distribution corresponding to these small impact parameter events is modeled using a multi-cascade charge equilibration model. We show that for bare Ne¹⁰⁺ ions, the initial emptiness of the n=1 shell leads to higher rates for the stabilization on the projectile of the first two electrons.
