AB  - A coherent X-ray diffraction study of a single colloidal crystal grain composedof silica spheres is reported. The diffraction data contain Bragg peaks andadditional features in the form of Bragg rods, which are related to the stacking ofthe hexagonally close-packed layers. The profile of the Bragg rod shows distinctintensity modulations which, under the specific experimental conditions usedhere, are directly related to the stacking sequence of the layers. Using a modelfor the scattered intensity along the Bragg rod for an exact stacking sequence ofa finite number of hexagonally close-packed layers, it is found that a doublehexagonal close-packed stacking sequence is present in the colloidal crystalgrain. This analysis method opens up ways to obtain crucial structuralinformation from finite-sized crystalline samples by employing advancedthird-generation X-ray sources.
