Neutron scattering in a Leibfried-Brenig spectrum space lattice

The classical high-temperature limit of the pair self-correlation function for a system of harmonic oscillators as introduced by Sunakawaet al. is applied to a lattice whose vibrational spectrum is described by a Leibfried-Brenig approximation. The resulting neutron scattering cross-section is discussed qualitatively; it is shown that the principle of detailed balance is fulfilled.
