title: Depolarized light scattering spectroscopy of Ca0.4K0.6(NO3)(1.4): a reexamination of the "knee".
abstract: The "knee" found in the depolarized light scattering spectra of Ca0.4K0.6(NO3)(1.4) at low temperatures by G. Li, W.M. Du, X.K. Chen, H.Z. Cummins, and N.J. Tao [Phys. Rev. A 45, 3867 (1992)] appears to have been an experimental artifact. The origin of this feature is analyzed, and its implications for the mode coupling theory of the liquid-glass transition are considered.
