Scattering geometry in reciprocal space. (a) Scattered intensity defined in the detector plane in the polar coordinate system, . (b) Ewald sphere construction. Here is the wavevector of the incident beam directed along the axis, is the wavevector of the scattered wave with the scattering angle . The scattering vector is decomposed into two components that are perpendicular and parallel to the direction of the incident beam. Definition of the momentum transfer vectors in the derivation of the two-point (c), and three-point CCFs (d).
