Abstract
Diffuse scattering in decagonal phases is due to deviations from strict aperiodic and periodic order in the quasiperiodic plane and along the unique direction, respectively. Results from X-ray (synchrotron) and neutron diffraction experiments, mainly carried out with decagonal Al-Ni-Co, are presented. Most prominent are diffuse maxima, diffuse streaks, phason affected reflection profiles, and diffuse layers perpendicular to the unique axis. Disorder models in decagonal qc-structures, in particular lamellar domain-like ordering in super-space are outlined. The terms structure and phase in context with disordered structures are discussed.
