Abstract

A structure of an icosahedral Al-Pd-Re (i-Al-Pd-Re) quasicrystal analyzed by using an imaging plate Weissenberg camera and synchrotron radiation is reported for the first time. An initial model for the refinement has been determined by the low-density elimination method (LDEM). The electron density in six-dimensional space showed that this phase is isostructural to i-Al-Pd-Mn, and its Re sites correspond to the Mn sites in the latter. The structure refinement gave an R-factor of 0.076 for 1312 independent reflections. Some atoms are shifted significantly from their ideal positions and some atom sites in i-Al-Pd-Mn are unoccupied.
