a center of inversion for diffraction amplitude), the continuous diffraction pattern has sixfold symmetry. If two such objects are placed near to each other (c), then the FT of both (d) will resemble (b) except for the interference function between them. When enough objects are placed in ...
The diffraction pattern of the annealed sample showed two additional weak reflections, which could be indexed as a super lattice structure U 3Mo derived from the bcc cell by a /1 1 0/1 1 0/0 0 1/ type lattice transformation. The disorder–order phase transition leading to the formation ...
The extra peaks observed at 29.9°, 53.1°, 62.2°, 78.5° are additional peaks due to bcc crystal structure of PdCu characteristics of new planes [23]. Thus IM will have different XRD pattern compared to a composition of the alloy, monometallic Pd and Cu. In case of supported IMCs, ...

Homework Statement I apologize for the blurriness in my title, I couldn't find anything better to fit within the length limit. The problem I'm stuck with, paraphrased, is to derive the formula for the diffraction pattern of a double slit, as found in the Young experiment, from the Fraunh...
The Common Volume Function (CVF) of G5, calculated according to Leonardi et al.60, provides a nearly perfect model for the domain size profile component in the G5 pattern. This is shown in Fig. 11a for the crystal- lographic case, where the only source of line broadening is the ...
The preliminary data on cold-worked cerium, although of lower accuracy than that normally attainable in this type of work, nevertheless showed peak displacements in the Debye-Scherrer pattern that were in most cases in the direction theoretically predicted for relatively low probabilities of extrinsic ...
In this chapter the ways how to use mathematics methods to deal with issues on electron diffraction and crystallography are described. These issues include the prediction of an arbitrary zone of diffraction pattern based on the known orientation relationship (OR), prediction of the possible ORs and...
