摘要：
We report for the first time the direct determination of x-ray-reflection phases of a large-unit-cell volume, 350000 angstrom 3, macromolecular crystal using three-beam diffraction. The crystal polarity (enantiomorph) is determined unambiguously from the peak-intensity measurement. Quantitative analysis of phase angle, with a scaling scheme for intensities, is presented.
