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. See more Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics See more • Coordinates in square brackets such as [100] denote a direction vector (in real space). • Coordinates in angle brackets or chevrons such as <100> denote a family of directions which … See more Crystallography is used by materials scientists to characterize different materials. In single crystals, the effects of the crystalline arrangement of atoms is often easy to see … See more A number of women were pioneers in X-ray crystallography at a time when they were excluded from most other branches of physical science. See more With conventional imaging techniques such as optical microscopy, obtaining an image of a small object requires collecting light with a magnifying See more Some materials that have been analyzed crystallographically, such as proteins, do not occur naturally as crystals.
