New page

In [[scattering]], the '''momentum transfer''' is a vector in the 3D [[reciprocal-space]] that denotes the change in momentum between the incoming and scattered rays. It thus describes the interaction between the radiation and the sample. This quantity is also frequently called the '''scattering vector''', and is normally denoted by <math>\mathbf{q}</math> or <math>\vec q </math>, in vectorial form, or simply by ''q'' when only the magnitude of the vector is relevant (for 1D scattering; e.g. [[TSAXS]]).

In the majority of scattering experiments ([[SAXS]], [[WAXS]], [[GISAXS]], [[GIWAXS]], etc.), the interaction is elastic, meaning that the energy (wavelength) of the incident and scattered photons are equal. In this case, the scattering vector is confined to the surface of the [[Ewald sphere]].
