Abstract

We report a light-scattering observation of relaxation in [Ca(NO3)2]0.4-(KNO3)0.6 in the vicinity of the liquid-glass transition. The spectra exhibit self-similarity with I()=A/1-a over a spectral range of nearly 3 orders of magnitude in both the liquid and glass phases. This result agrees with predictions of mode-coupling theories of the glass transition. However, the value of a is strongly temperature dependent, a result not predicted by the theory. The spectra are strongly depolarized with a depolarization ratio of 0.75.
