| Abstract: | We study the conditions of the mutual distinction of the structures of the 12-atom close-packed clusters (fcc, hcp, icosahedral) in the presence of thermal fluctuations via analysis of the distribution function in the space of structural invariants. It is shown that the close-packed types of local structure remain distinct well above the melting point. |
