Abstract

High-precision determination of the absolute value of lattice parameter for cubic single crystals is demonstrated by the example of silicon using coincidental multi-beam X-ray diffraction realized by superposition of two three-beam reflections at fixed sample temperature. Based on a semi-kinematical approximation of X-ray scattering theory, the algorithm for calculation of multi-beam diffractograms is developed enabling a more thorough quantitative analysis of experimental results.
