The separation of coherent and incoherent cross‐sections in inelastic neutron scattering using polarized nuclear targets

The coherent and incoherent neutron scattering cross‐sections have different dependences on the polarization of neutrons and target. This fact can be used to separate the coherent and incoherent part of the inelastic cross‐section and to enhance the otherwise very weak coherent scattering in the cases of H1 and V51. Some details of this method are studied and the results are applied to the case of ZrH2. It seems evident that the dispersion curves of phonons in ZrH2 can be measured by this method.
