| Popis: | The cross-section for scattering of neutrons by photons is high in crystals. Since a photon in a crystal (polariton), being a superposition of transverse photon and Coulomb excitations (optical phonon, exciton, etc.), excites during its propagation the motion of the nuclear subsystem, the cross-section for scattering of neutrons by photons turns out to be proportional to the neutron scattering cross-section for nuclei and the phonon strength function at the polariton frequency. |
