INELASTIC LIGHT SCATTERING FROM THERMAL FLUCTUATIONS IN GASES by NOEL
We have studied the Brillouin spectrum of light scattered by the dilute monatomic one component gases xenon and helium and by the xenon-helium binary gas mixture. In a one component monatomic gas the scattered light spectrum for a scattering process with momentum transfer, K, and energy transfer, w, is proportional to the power spectrum, S(K, W), of fluctuations in the density of the gas. In a ...
متن کاملFluctuations in Scattered Light
Fluctuations in scattered light constitute some of the most familiar natural optical phenomena, including the twinkling of starlight, the glittering of sunlight on a rippled water surface and the shimmering of distant objects on a hot day [1]. These effects are geometrical in origin being a consequence of refraction by large-scale random variations in refractive index. Fluctuations of this kind...
متن کاملFluctuations of light scattered by fractal clusters
Fluctuations in light scattering from a finite ensemble of fractal clusters are studied numerically and theoretically. It is shown that, for a wide range of wavelengths and angles, relative fluctuations in the scattered intensity are very close to 1 and do not depend on the number of monomers N in fractal clusters (whereas they are proportional to 1/AN for trivial clusters). The relations descr...
متن کاملSpectrum of the Depolarized Rayleigh Light Scattered by Gases of Linear Molecules
The spectrum of the depolarized Rayleigh light scattered by a gas of linear molecules is calculated by a kinetic theory approach based on the Waldman-Snider equation. Collisional and diffusional broadening are studied. The line width is related to relaxation coeff icients which are collision brackets obtained from the linearized Waldmann-Snider collision term involving the binary molecular scat...
متن کاملA. Spectrum of Coherent Light Scattered from a Turbulent Jet
The work of our group is being carried out as a cooperative effort with Giorgio Fiocco, of the European Space Research Institute (ESRIN), Frascati, Italy. For the most part, this research is directed toward problems of interest in the atmospheric sciences. In particular, we have conducted spectral analyses of the light scattered from a laser beam by atmospheric molecules and aerosols, using a F...
