Abstract :
Disorder in decagonal quasicrystals is studied by “contrasting methods”, i.e. by joint analysis of X-ray and neutron data and by use of the anomalous dispersion method, to learn about the relative influence of the transition metals. First experimental results with decagonal Al–Ni–Co samples of different origin are discussed qualitatively. A comparative study of Patterson maps from neutron and X-ray Bragg data of d-Al72.5Ni16.5Co11 gives direct evidence for particular sites occupied by Co.
