Abstract
The activity of the Working Group of Mineralogy at Photon Factory was reported, and the earliest results of the following items were briefly presented : x-ray toaograahy of a cube-shaped diamond, reinvestigation of the lilianite structure, examination of single crystal, diffraction data collection from micro-size specimens using a four-circle diffractometer., the absolute orientation of hemimorphite, cation ordering in the structure of Cu9As4Se13, modulation in α-Al2O3 crystallite formed in the process of dehydration of diaspore, RDF study employing anomalous scattering effect, cation distribution in pentlandite at high temperature, a trial of high temperature high pressure single crystal x-ray study using high temperature diamond anvill cell on SOR beam, superstructure of tetrataenite from the Saint-Severan meteorite, diffuse scattering from β-PbF2, measurement of diffuse streaks scattered by fine segregates of β-MnO2, and others.
