SUMMARY
The unit of atom scattering factor is defined as e/atom, which refers to the scattering of X-rays primarily by electrons. This unit is derived from calculating the scattering of a single free electron and multiplying it by the number of electrons per atom. At larger scattering angles, the spatial distribution of electrons around the nucleus must be considered, leading to the form factor. For diffraction analysis, the positions of the atoms are also crucial in determining the scattering factor.
