Mott Differential Cross Section of Elastic Scattering

The Mott differential cross-section [1] is given by,

                Mott differential cross-section ---------------------- [4552]

where θ -- Elastic scattering angle
          f(θ) and g(θ) -- Scattering amplitudes

The Mott cross-section derived from the relativistic wave equation of Dirac can be applied to calculate the elastic scattering of low-energy electron in materials.
