The structure of decagonal Al₇₀Ni₁₅Co₁₅

Abstract

The quasiperiodic structure of decagonal Al 70 Ni 15 Co 15 was determined on the basis of X-ray single-crystal intensity data using the n-dimensional embeding method. Centrosymmetric five-dimensional space group P10 5 /mmc, three-dimensional reciprocal and direct quasilattice parameters: a i * =0.2636 (1) A -1 , i=1,..., 4, a 5 * =0.24506 (3)A -1 , a i =3.794 (1)A, i=1,..., 4, a 5 =4.0807 (3) A
