Phasing diffuse scattering. Application of the SIR2002 algorithm to the non-crystallographic phase problem

Autor: Carrozzini, B., Cascarano, G. L., De Caro, L., Giacovazzo, C., Marchesini, S., Chapman, H. N., He, H., Howells, M. R., Wu, J. S., Weierstall, U., Spence, J. C. H.

Publikováno v: Acta Cryst. A60, 331-338 (2004).

A new phasing algorithm has been used to determine the phases of diffuse elastic X-ray scattering from a non-periodic array of gold balls of 50 nm diameter. Two-dimensional real-space images, showing the charge-density distribution of the balls, have

The decomposition of a powder diffraction pattern consists of the extraction of the intensities of the individual reflections from the experimental profile. The process is crucial for structure determination from powder diffraction data, but its accu

Section A, Foundations of crystallography/anno:2013/pagina_da:408/pagina_a:412/intervallo_pagine:408–412/volume:69

A new study of the sigmaA parameter has been undertaken to understand its behaviour when the diffraction amplitude distributions are far from the standard Wilson distributions. The study has led to the formulation of a new statistical interpretation
