Abstract

The structure refinement of i-Al-Pd-Mn quasicrystals using an IP-Weissenberg camera is reported. A 6D model proposed previously [Mater. Sci. Forum 150-151 (1944) 211] was used as an initial model for the refinement and was modified during the refinement. The final model includes 91 structural parameters and gave R-factors of Rw = 0.053 and R = 0.054 for 377 independent reflections. This suggests that an IP-Weissenberg camera gives a reliable data set for quasicrystals which includes many weak reflections. The structure includes two 20
