| Outline of Final Research Achievements |
In this project, experimental and theoretical investigations have been performed focusing on decagonal quasicrystals in order to make progress on the structure analysis of unsolved quasicrystals. Single crystals of an approximant crystal to decagonal quasicrystals in the Al-Pd-Ru system have been grown successfully. Average structure of the Zn-Mg-Dy decagonal quasicrystal has been determined by means of five-dimensional structure analysis. A feasible five-dimensional structure model for an Al-Cu-Rh decagonal quasicrystal was constructed. Multiple diffraction phenomena in an Al-Cu-Ru icosahedral quasicrystal have been evaluated by using an originally developed simulation code, which is based on the kinematical theory for X-ray diffraction.
