Figure 2
Section from the hk0 layer of ACT-71. Some of the reflections violating the extinction rule h + k = 4n and h, k = 2n (n = integer) of the space group ![[Fd{\bar 3}m]](teximages/sn5082fi32.gif) are marked. Some reflections having similar intensities at equivalent positions according to the vertical mirror plane are marked by arrows, while examples of reflections showing strong disagreements are marked by circles. The latter effect might be caused by Umweganregung. The pattern ranges from −0.3 to 0.3 Å−1 along the horizontal direction and from −0.05 to 0.4 Å−1 along the vertical direction. To obtain a better visual impression of the intensities, the pattern was convoluted with a Gaussian with FWHM of 0.00125 Å−1. The off-lattice spots in the pattern may originate from small grains attached to the surface of the crystal, and the white arc in the top left part of the image from the blind areas of the PILATUS 6M detector. |
