| Abstract: | The structures of giant icosahedral close-packed clusters are considered in the framework of the local approach. A specific four-dimensional construction that consists of tetrahedra and octahedra and has symmetry of the {3, 3, 5} polytope is determined. It is demonstrated that the Pd561 cluster is an icosahedral twin of fragments of both the face-centered cubic lattice and the hexagonal close packing simultaneously.Original Russian Text Copyright © 2005 by Fizika i Khimiya Stekla, Shevchenko, Samoilovich, Talis, Madison. |
