Abstract

The Zeno (Critical Fluid Light Scattering) experiment is the culmination of a long history of critical fluid light scattering in liquid-vapor systems. The major limitation to making accurate measurements closer to the critical point was the density stratification which occurs in these extremely compressible fluids. Zeno when flown was to allow determination of the fluctuation decay rates at a pair of supplementary angles in the temperature range 100 mK to 100 µK from Tc in a sample of xenon accurately loaded to the critical density.
