Crystallographic zone

WebDirections, Planes and Zone Axes. Here we introduce the concepts relating to the labelling and representation of crystallographic planes and directions. This is usually done using the Miller or Miller-Bravais notations, which are described below. Crystallographers often explicitly state the type of beam used, as in the terms X-ray crystallography, neutron diffraction and electron diffraction. These three types of radiation interact with the specimen in different ways. X-rays interact with the spatial distribution of electrons in the sample.
