Theoretical and experimental study of the depolarization of the Rayleigh radiation scattered by compressed rare gases
Abstract
A theoretical interpretation is presented of the pressure-induced depolarization of the Rayleigh light scattered by compressed rare gases. The calculation is based on the hypothesis of fluctuations for the effective field in connection with the induced dipole interaction. For low gas densities, the cancellation due to a regular environment is taken into consideration. Theoretical values of the depolarization ratio, given by this interpretation, are compared with those obtained in experiments on compressed argon, between 15 and 1500 bars. The agreement is good in the low density range, but becomes poor for high densities.
