And his methods of X-ray diffracted beam monochromatization.
2.
Inelastic scattering experiments normally require a monochromatization of the incident or outgoing beam and an energy analysis of the scattered neutrons.
3.
Monochromatization is not needed in echo techniques ( neutron spin echo, neutron resonance spin echo ), which use the quantum mechanical phase of the neutrons in addition to their amplitudes.
