ANISOTROPIC LIGHT SCATTERING BY INNER FIELD FLUCTUATIONS IN A DENSE MONATOMIC GAS,
Abstract
The intensity of light scattering by monatomic gases is calculated by a new method which is particularly suited to analyzing the effect of collective phenomena such as the fluctuations of the inner field. The Fourier coefficients of the polarizability density are used as stochastic variables and their relation to the atomic form factor and the particle density is established. The effective inner field for a specific particle configuration is obtained as an iterative solution of an integro-differential equation, and is used for calculating the scattering intensity. This intensity is then averaged over all particle configurations. At ordinary pressures Rayleigh's scattering formula is confirmed, but at high pressures observable corrections to his formula are obtained. In particular, scattering is found depolarized contrary to Rayleigh's theory and to some recent work. (Author)
