Abstract
The fine structure of the Rayleigh line wing depolarized spectrum in a form of a triplet caused by the light scattering by transverse hypersonic waves was detected in a critical solution with a closed stratification region at low temperatures. The propagation velocity of transverse hypersound and its absorbance were measured. The temperature dependence of the shear modulus in solution was calculated. The temperature dependence of the shear modulus was compared to temperature dependences of limiting bulk elastic moduli. The results obtained suggest that the solution structure changes in passing through the stratification region at changing temperature.
