Wide-angle x-ray diffraction theory versus classical dynamical theory

TL;DR

This paper compares classical and wide-angle dynamical x-ray diffraction theories, demonstrating that wide-angle theory aligns well with Zaus correction and can be applied without dispersion theory.

Contribution

It introduces a method to incorporate the true angular variable in wide-angle x-ray diffraction without relying on dispersion theory.

Findings

Wide-angle x-ray diffraction theory agrees with Zaus correction.

True angular variable can be used without dispersion theory.

Wide-angle theory offers an accurate alternative to classical dynamical theory.

Abstract

In this article we provide a comparison of classical dynamical x-ray diffraction theory with the dynamical theory for the wide-angle case. It is shown that it is possible for the true value of the angular variable to be introduced without application of the dispersion theory. Wide-angle x-ray diffraction theory is in an excellent agreement with Zaus correction of the angular parameter.
