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.

WebCrystallographic axes are imaginary lines of reference inside a crystal that intersect at a common point (the crystal centre), and to which crystal faces can be referenced. Any crystal has either 3 or 4 crystallographic axes. The angles between these axes are known as the interaxial angles. WebThe crystallographic axes used in this system are of equal length and are mutually perpendicular, occurring at right angles to one another. All crystals of the isometric system possess four 3-fold axes of symmetry, each of …
