A Large Dodecahedral Cluster Containing about 480 Atoms in a 2/1 Cubic Crystalline Approximant


  A dodecahedral atom cluster, which is the largest atom cluster with icosahedral symmetry, was found in a cubic crystalline phase of b-(AlPdMnSi) with a lattice constant of 2.0211 nm. The atom cluster has a diameter of about 2.6 nm and contains about 480 atoms. The result was published in J. Phys. Soc. Jpn. (Vol. 67, p.1501xj.
