Abstract
Some issues related to the modelling of the powder diffraction pattern of a nanocrystalline material are proposed. Serious misunderstanding of the results can occur when the peak profiles are not correctly considered in reciprocal space, or when the subtle details of the peak shape due to the peculiar microstructure of the material are not taken into account.
Keywords: Powder diffraction; Diffraction line profile; Line profile analysis; Nanocrystalline materials; Rietveld method
