Abstract:
A new rotation function in Patterson space is described. An image-seeking function can be defined as a criterion of fit between the observed Patterson map and a suitable vector set extracted from a specially calculated Patterson map of the search model. The behaviour of image-seeking functions has appeared to be heavily dependent on certain relations between some statistical parameters of both maps. A new algorithm, which carries out the crucial step of selecting the appropriate vector set from the search model, has been established. As a consequence of the combination of these two preceding results, a new vector-search rotation function has been proposed and tested.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
