Contrary to the case of Ag/sub 7/ where fragmentation is crucial to explain the data, the deposition leads at low temperature to noncompact structures localized around the impact point. We propose a model in which morphology changes take place between 200 and 300 K resulting in well-separated compact structures.atom surface impactmetal clustersmolecular dynamics methodpalladiumsilver morphologyevolutionsize selected metallic clustersmetal surfaceAg 19 +Pd100size selected depositiontotal kinetic energiesthermal energy atom scatteringmolecular dynamics simulationslow temperaturenoncompact structuresimpact pointmodel95 eV20 eVPdAg A6146 (Solid clusters including fullerenes and nanoparticles)A7920N (Atom molecule and ion surface impact)A61A79A6A7text::journal::journal article::research article
