Diffraction from crystals Structure factor The structure factors are proportional to the Fourier coefficients of the crystal potential. We assumed discrete, spherically symmetric atoms. The position of atom m can be specified by a short vector dm that points to a location in the unit cell: 2 atoms e i m m m Ff g d g
Bragg diffraction occurs when radiation of wavelength λ comparable to atomic spacings, is scattered in a specular fashion (mirror-like reflection) by the atoms of a crystalline system, and undergoes constructive interference. For a crystalline solid, the waves are scattered from lattice planes separated by the distance d between successive layers of atoms. When the scattered waves interfere const… WebJul 8, 2015 · An example of an X-ray diffraction pattern (one-minute rotation image) produced by a randomly oriented single-crystal specimen on a 2D detector. ...
