Structural slowing down and depolarized light spectra in dense noble gas fluids

Abstract

We argue that the narrowing at increasing densities of the light spectra obtained for Ar and Kr by An et al.(J. Chem. Phys., 1979, 70, 4626) using depolarized interaction-induced light scattering techniques is due to the slowing down of structural relaxation in dense fluids which is observed in neutron scattering experiments on He, Kr, Ar and Rb.
