By using the selection rules for the CaF2 structure and a combination of the neutron scattering data and theoretical phonon dispersion curves, we were able to

The shape of this peak then depends upon the detailed behaviour of the lifetime and frequency of the long wavelength optic mode.. The anharmonicity

scattered radiation can usually be enhanced by choosing the exciting frequency to be close to an absorption line or band of the crystal. For scat- tering by
