Abstract: 
The stopping power of large (H2)n-clusters in silicon is analyzed as a function of the cluster size and the cluster velocity. A dielectric formalism is used to describe the electronic interaction between the projectile and the target. The intramolecular and intermolecular interference effects in the cluster energy loss are evaluated as a function of the cluster velocity. For high velocities and large clusters the intermolecular collective effects dominate in the cluster stopping power. For each cluster velocity we find a resonant cluster size for which the intermolecular stopping power clearly shows a maximum and it saturates to a constant value for larger clusters. The radius of this resonant cluster and the maximum stopping power are proportional to the cluster velocity.
