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 feature of all form factors is that they involve a Fourier transform of a spatial density distribution of the scattering object from real space to momentum space (also known as reciprocal space). For an object that is spherically symmetric, the spatial density distribution can be expressed as a function of radius, $\rho(\mathbf{r})$ , so that the form factor, $f(\mathbf{Q})$ , is defined as
