Angular X-ray Cross-Correlation Analysis Applied to the Scattering Data in 3D Reciprocal Space from a Single Crystal
Abstract
We propose an application of the Angular X-ray Cross-Correlation Analysis (AXCCA) to the scattered intensity distribution measured in three-dimensional (3D) reciprocal space from a single crystalline sample. Contrary to the conventional application of AXCCA, when averaging over many two-dimensional (2D) diffraction patterns collected from different randomly oriented samples is required, the proposed approach gives an insight into the structure of a single specimen. This is particularly useful in studies of defect-reach samples that are unlikely to have the same structure. Here, we demonstrate an example of a qualitative structure determination of a colloidal crystal on the simulated as well as experimentally measured 3D scattered intensity distributions.
