Abstract
Ellipsometric measurements at the liquid-liquid interface of a critica l ionic Ising mixture yield a decrease in the ellipticity <(rho)over b ar> as the reduced temperature t is decreased (for t>0.002) in contras t to a t(beta-nu) power-law divergence found for nonionic Ising mixtur es. From this surprising result we infer the existence of an anisotrop ic interface. A model of such an interface is used to calculate theore tical <(rho)over bar> data, which capture some of the characteristics of the experimental results.
