Abstract : Measurements are reported for the intensity and spectral width of light scattered by concentration fluctuations near the critical mixing point of the binary liquid mixture 3-methylpentane-nitroethane. The data were taken at the critical concentration as a function of temperature and scattering angle. The intensity data allows one to determine the susceptibility and the equilibrium correlation length as a function of temperature. (Author)
