Diffraction model¶
How a crystal structure and a beam produce the intensities the calculation predicts.
| Topic | Questions answered |
|---|---|
| Rietveld method | How do structures, profiles and corrections form a powder pattern? What does the fit minimise? |
| Crystallography | How do the cell, symmetry, reflection indices and multiplicities determine the diffraction geometry? |
| Scattering and structure factors | How do radiation, atomic positions, occupancy and scattering-data sources affect intensity? |
| Magnetic structures | How are magnetic symmetry, moments, form factors and the magnetic intensity calculated? |
| Atomic displacement | What do Biso, Uiso, Bani, Uani and beta mean? |
