Query: Rayleigh Scattering in Rare Gas Liquids   The Rayleigh scattering length has been calculated for rare-gas liquids in
the ultraviolet for the frequencies at which they luminesce. The calculations
are based on the measured dielectric constants in the gas phase, except in the
case of xenon for which measurements are available in the liquid. The
scattering length mayplace constraints on the design of some large-scale
detectors, using uv luminescence, being proposed to observe solar neutrinos and
dark matter. Rayleigh scattering in mixtures of rare-gas mixtures is also
discussed.
