Abstract: | The coupled system of phonons and librons is treated in the Random Phase Approximation. The short range correlations are taken into account by an effective Hamiltonian. Dispersion curves and spectra are calculated for both the fcc and hcp phases. All calculations are performed a) with quadrupole-quadrupole forces only b) including the other anisotropic forces. |
