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.
