Abstract
The height and temperature dependences of the total scattered light intensity and Rayleigh line width for a binary mixture of methanol-hexane were studied near the critical consolution point by means of static and dynamic light scattering. The temperature dependence of the diffusion coefficient along the critical isochore and coexistence curve, and the field of dependence of the diffusion coefficient as a function of height were studied. The correlation length temperature dependence along the critical isochore, the coexistence curve, and the field dependence along the critical isotherm were analyzed using Ferrell’s formula derived in the framework of the Kawasaki coupling mode theory.
