Abstract
By use of light scattering techniques a careful investigation has been made of the time dependence of the concentration fluctuations near the critical point of a binary liquid mixture. The experiments reveal deviations from exponential decay of these fluctuations at temperatures within 20 mdeg from the critical temperature. The observed deviations from exponential decay are in agreement with a recent theoretical prediction of Bhattacharjee and Ferrell.Keywords
