Summary

We show that how elastic the scattering of external particles (usually photons or neutrons) by a crystal allows us to determine experimentally the lattice structure. We also show that the inelastic scattering of thermal neutrons due to phonon absorption or emission reveals the phononic dispersion relation; a comparison with the corresponding theoretical results is presented. Explicit expressions for these elastic and inelastic cross-sections are obtained.
