Résumé

Under impact of 150-keV/atom Au+n projectiles (1<~n<~9) on gold targets the emission yield of anionic clusters increases much faster with n than expected from simple proportionality. Moreover the anion size distribution is much wider for bombardment by clusters. The cluster yield enhancements reflect the size dependence of the cluster stability according to the electronic shell structure. Accordingly, the most intense emission is observed for Au−7: under Au+9 impact the Au−7 yield per incident atom is enhanced by a factor of ∼6.
