In physics, the atomic form factor, or atomic scattering factor, is a measure of the scattering amplitude of a wave by an isolated atom. The atomic form factor depends on the type of scattering, which in turn depends on the nature of the incident radiation, typically X-ray, electron or neutron. The common … See more X-rays are scattered by the electron cloud of the atom and hence the scattering amplitude of X-rays increases with the atomic number, $${\displaystyle Z}$$, of the atoms in a sample. As a result, X-rays are not very … See more The relevant distribution, $${\displaystyle \rho (r)}$$ is the potential distribution of the atom, and the electron form factor is the Fourier transform of this. The electron form factors are normally calculated from X-ray form factors using the Mott–Bethe formula. … See more There are two distinct scattering interactions of neutrons by nuclei.
