While the description of the scattering process of neutrons—on the samples they are intended to explore—requires full quantum mechanical description for prediction and interpretation, the propagation of neutrons within the neutron scattering instruments can be nearly always described and controlled with all required precision by rules of geometrical optics. This is the basis of spin labeling methods, which allow us to individually tag each neutron with the help of its spin with information on its initial state when arriving to the sample and re-label it before detection with information of the change of its state by the scattering interaction with the sample. Finally, by detecting the expectation value averages of intensity and polarization state of the beam, we can directly observe information on neutron energy and/or momentum transfer with unique resolution and beam intensity.
