Diffraction intensity ($I\propto |F{|}^2$)

For coherent elastic diffraction, the intensity associated with a given scattering amplitude is proportional to its squared modulus. Integrated powder diffraction intensities additionally include the powder diffraction multiplicity, Lorentz-polarization factor, Debye–Waller factor, absorption and instrument corrections. A peak's height is not its integrated intensity unless its profile width and shape are also specified.
