X-Ray Fluorescence Experiments with Polarized X Rays [PDF]

open access: yesAdvances in X-ray Analysis, 1974
AbstractTwo methods of obtaining polarized x-rays for fluorescence experiments are discussed. Compton scattering from a low-Z scatterer is the usual method used in such experiments. The polarization of x-rays undergoing anomalous Borrmann transmission in a dislocation-free crystal is also described and preliminary results are presented.

Analysis of geometric factors for an X-ray fluorescence analyzer designed via the Monte Carlo method

open access: yesMATEC Web of Conferences, 2016
This paper presents a theoretical study on the design of an X-ray fluorescence (XRF) analyzer. The relative geometric positions of the analyzer’s source, detector and specimen are emphasized, which impacts the analyte’s characteristic X-ray fluorescence ...

Self-transformation of solid CaCO3 microspheres into core-shell and hollow hierarchical structures revealed by coherent X-ray diffraction imaging

open access: yesIUCrJ, 2022
The self-transformation of solid microspheres into complex core-shell and hollow architectures cannot be explained by classical Ostwald ripening alone.
