Line 1:

The '''dynamical theory of diffraction''' describes the interaction of [[wave field]]s with a regular lattice. The wave fields traditionally described are [[X-rays]], [[neutron radiation|neutron]]s or [[electrons]] and the regular lattice atomic crystal structures or nanometer scaled multi-layers or self arranged systems. In a wider sense, similar treatment is related to the interaction of light with optical band-gap materials or related wave problems in acoustics.
