 The '''atomic form factor''' is the [[scattering]] contribution from a single, isolated atom. The [[form factor]] is generally described as encoding the ''shape'' of a scattering object. The atomic form factor thus encodes the shape of an atom. More specifically, it is the [[Fourier transform]] of the atom's spatial distribution.
-The interpretation of 'spatial distribution' depends on the kind of scattering. [[X-rays]] are scattered from an atom's electron cloud; thus the scattering amplitude scales with the atomic number (''Z''). The scattering interaction for each element is tabulated as the "[[atomic scattering factor]]". For [[neutrons]], the scattering interaction instead occurs with the nucleus; which leads to a non-intuitive variation of the [[neutron scattering length]] across the periodic table. (Neutron scattering also has a [[magnetic scattering]] component, owing to nuclear spin.)
