Abstract
High-resolution electron microscopic images of a melt-quenched Al-14 at%Mn alloy displaying an icosahedral point-group symmetry were interpreted in terms of projections of a three-dimensional space filling of the Penrose type skeleton, which was recently completed by Ogawa (J. Phys. Soc. Jpn. 54 (1985) 3205). Fitting with the observed images, two types of basic golden rhombohedra, acute and obtuse ones, are estimated to have the edge-length of 0.48 nm, and two atomic structure models are proposed.Keywords
