where is the electron scattering cross-section and is the x-ray scattering cross section. This is a function of , the scattering vector of momentum transfer cross section in reciprocal space (in units of inverse distance), and Z is the atomic number of the atom. In the equation is Planck's constant, is the vacuum permittivity.
The units of the scattering factor are
