Phase problem

Phase problem

In X-ray crystallography, the gap between the requirements for reconstruction of a model - for each reflection (defined by the angle of its diffraction), the amplitude (related to intensity) and phase (a measure of the alignment of the wave function with that of other reflections) - and the experimentally accessible quantities, the intensities of each reflection.
