λ/2 contamination in X‐ray diffraction data – the impact of heavy atoms

The impact of very different values of f′ and f′′ and of absorption coefficients for the wavelengths λ and λ/2 for heavy elements, and the effect of the difference in wavelength dispersion on the profile of the corresponding Bragg reflections, are discussed with respect to the correction of diffract...
