The structure of evaporated gold particles were examined through the (111) lattice image observation. The results obtained confirmed Ino's analysis (1966) that the particles are of multiple-twin structure and have external shapes of either decahedron or icosahedron. It was also found that the structures are already completed at the initial stage of deposition when the particle size in smaller than 20Å, but the particles no longer keep their initial structures when they grow beyond about 150Å in size. Neither gaps nor dislocations were observed in the particle image; instead, lattice images were found to be composed of lines not exactly parallel to each other, but slightly diverging outwards. These observed facts suggest that the particle nucleus consisting of several atoms forms the smallest unit of either decahedron or icosahedron and growth proceeds layer by layer of atoms on the nucleus.
