Rayleigh-Brillouin Scattering in Gaseous Mixtures He-Kr and Ar-Kr.

摘要

Measurements of Rayleigh-Brillouin spectra of gaseous mixtures helium-krypton and argon-krypton were performed over a range of concentrations and temperatures. The data were compared successfully with the theoretical spectra using the approximate equation of Cohen, Sutherland, and Deutch. For the first time, the effects of temperature changes upon the spectra were considered and successfully employed in the analytical expressions of Kestin et al. to determine the thermodynamic constants of our mixtures.
