The experimental determination of phases of reflections from mosaic crystals. 1. ZnWO4
Abstract
The signs of large numbers of phases of reflections from centrosymmetric crystals of ZnWO4 have been determined by methods outlined by Post Acta Cryst. (1979), A35, 17-21; (1983), A39, 711-718. Fifty-three n-beam interactions were selected to illustrate the phase determination procedure. Methods of extracting three-beam phase information from such interactions are discussed and illustrated.
