A beam of silver clusters of 3 nm average diameter is produced by the gas‐aggregation technique and deposited onto the NaCl (100) surface. Subsequent agglomeration leads in part to the growth of rodlike particles with the structure of truncated decahedra of typical dimensions 70 nm long and 10 nm diameter and a fivefold symmetry, as shown in the picture. A growth mechanism is inferred from a detailed analysis of electron microscopy data.
