The depolarized, interaction-induced light scattering spectrum of xenon gas at room temperature has been measured in the very low frequency region, by means of a high resolution, high contrast monochromator. In addition to the accurate determination of the bound dimers band, a positive contribution in excess of the calculated pair spectrum is observed at lower frequency.

Abstract
The depolarized, interaction-induced light scattering spectrum of xenon gas at room temperature has been measured in the very low frequency region, by means of a high resolution, high contrast monochromator. In addition to the accurate determination of the bound dimers band, a positive contribution in excess of the calculated pair spectrum is observed at lower frequency. A density analysis of this intensity excess shows that we have measured, for the first time, the intercollisional interference effect long ago predicted by Lewis and Van Kranendonk [Phys. Rev. Lett. 24, 802 (1970)].File in questo prodotto:
