Fig. 3From: Can quasicrystals survive in planetary collisions?Representative powder X-ray diffraction patterns of i-QC collected at room temperature in angle-dispersive mode (wavelength of 0.4133 Ã…) as function of pressure. Filled gray circles refer to Au used as a pressure marker. The diffraction peaks are indexed using Cahn indices (N, M) following the scheme proposed by Janot (1994)Back to article page
