WebNov 1, 2016 · The d -spacing can be computed according to Bragg’s law [2]: (1) d = n λ 2 sin θ where n is an integer, and it is assuming to be 1 for discussion convenience in this article; λ is the wavelength of the incident X-rays and 2 θ is the diffraction angle. WebThe atomic spacing of crystalline structures is usually determined by passing an electromagnetic wave of known frequency through the material, and using the laws of diffraction to determine its atomic spacing. The atomic spacing of amorphous materials (such as glass) varies substantially between different pairs of atoms, therefore diffraction ...
