Depolarized light scattering spectroscopy of Ca0.4K0.6(NO3)(1.4): A reexamination of the 'knee'

摘要

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,nd 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. [S1063-651X(99)02105-4]. [References: 14]
