| Abstract: | A beam of Pb clusters is produced with the inert gas aggregation method and probed by electron diffraction. Analysis of the
diffraction patterns indicates that average cluster size can vary between 3 and 7 nm, according to nucleation conditions.
The diffraction patterns from beams with larger average cluster size are very similar to patterns calculated from model decahedron
clusters, while those for smaller cluster size do not appear to have simple geometrical face-centred cubic, decahedral, or
icosahedral structure.
