Aim, Scope and Format
The ADD2026 School and Conference aim to deepen the understanding and to further the training of the various communities working with real-space data analysis methods in neutron and x-ray diffraction. The Fourier transformation of total-scattering diffraction data from reciprocal space into real space produces a Pair-Distribution Function (PDF) that represents a model-independent "snapshot" of the short-range atomic structure within the sample. The PDF(r) thus probes both static and dynamic local atomic correlations (as well as local magnetic spin correlations in the case of neutron diffraction). The measured PDF(r) can then be modelled or simulated using various software packages. These so-called "PDF-analysis" methods are therefore complementary to the well-known Rietveld method of refining diffraction data in Q-space that however provides only a space-time averaged picture of the sample's structure.
