Experimental measurements of the projectile angular distributions for 2.5-keV Ar81 ions capturing one to
five electrons from a gas-phase C60 target are presented. The number of captured electrons was determined by demanding a coincidence between the scattered projectile and a charge-state-analyzed intact C60 recoil ion. The results are compared to calculations based on a dynamical classical overbarrier model. Good agreement is obtained only if the influence on the projectile trajectory by the large polarizability of the C60 target is taken into account, thereby making the collective dielectric response of the cluster target observable in a scattering experiment.
