Evidence of Nonzero Critical Exponentηfor a Binary Mixture from Turbidity and Scattered Light Intensity Measurements

Abstract

Measurements of the turbidity and of the intensity of light scattered by a cyclohexane-aniline mixture in the vicinity of the critical point allow us to verify that scaling laws correctly describe the observed phenomena and yield precise values of the critical exponents $\gamma$, $\nu$, and $\eta$, of the correlation length $\xi$, and of ${\left(\frac{\partial \mu }{\partial c}\right)}_{P,T}$.
