Abstract
Measurements of light-scattering intensity and correlation lengths in all three coexisting phases in the mixture water + benzene + ethanol + ammonium sulfate are reported for temperatures near the tricritical point. A comparison with two sum rules predicted by a classical theory shows fairly good agreement in one case and significant deviations in the other. Possible explanations of the latter are discussed.Keywords
