Abstract
The angular distribution of light intensity scattered from a nonionic micellar solution of tetraethylene glycol n-decylether (C10E4) in water has been examined close to its critical point of mixing. Including multiple-scattering corrections to the light-scattering data, we have found the exponent γ=1.25±0.02 for the osmotic susceptibility χT and the exponent ν=0.63±0.01 for the long-range correlation length ξ in the temperature range of 1.03×10−4≤ε≤4.25×10−3, where ε=(Tc−T)/Tc. The values of the critical exponents obtained in this work are in good agreement with the theoretical and experimental ones for three-dimensional Ising systems.
