2.6. Real-space PDF calculation as a back-Fourier transform In the case of neutron scattering, the PDF calculation formalism is straightforward, as described by Keen (2001). This is because the neutron scattering length b is invariant with scattering vector magnitude Q. In the case of X-ray scattering, the atomic form factor f(Q) shows strong damping with Q and the Q dependence differs for different elements.
