Abstract
A careful examination of the peak profiles, peak shifts and peak separations of Bragg reflections, which are inherent in the disordering of quasicrystal, is carried out using an x-ray diffraction method for decagonal Al-Pd-Mn single quasicrystals. The full widths at half-maximum (FWHM) of the Bragg reflections along the longitudinal direction (L) have no or -dependence whereas those for both transverse directions, which are perpendicular to the L direction in an aperiodic plane and with a periodic axis, have linear -dependence. Notable peak shifts and separations of Bragg reflections are observed. The absolute values of the shifts are found to be proportional to . The peak shifts and separations are analysed in terms of linear phason strains.
