Stopping Power of Large Molecular Clusters in Cold and Heated Solids
The energy lost per particle and per travelled path length for a cluster of ions moving in a solid target, shows important differences-usually called vicinage effects- with respect to the energy loss of the separated ions [1–5]. The origin of this effect is the interference in the electronic excitations of the target due to the correlated motion of the penetrating ions. The effect has been theoretically explained [1,2] as interference effects in plasmon and single-particle excitations, but current research on inertial-confinement fusion using ion beams [6,7], and recent beam-target experiments with large molecular clusters [8–10], rise new interest in the evaluation of correlation effects in the stopping of ion clusters in cold and heated solids.
