Abstract

A determination is made of the temporal evolution of the momentum autocorrelation function for a noninteracting gas constrained by walls. A frequency-dependent dielectric constant is calculated from the latter by applying an appropriate Kubo relation. Deviations from the Drude conductivity are obtained which, for high frequency and/ or large systems, are found to be ∼ o(102/βmω2L2), where L is the spatial dimension of the assembly and ω the frequency of the applied field. A similar calculation is performed to determine the effects of boundaries upon measurements of scattering cross sections for slow neutrons. It is found that, for realistic experimental conditions, wall perturbations are unlikely to be of importance.
