Vv. Krotov et al., THE DIFFUSION MECHANISM OF THE PROPAGATION OF LIGHT IN FOAMS, Colloid journal of the Russian Academy of Sciences, 57(5), 1995, pp. 653-656
The attenuation factor was experimentally measured for light that pass
es through a layer of foam. The propagation of light in foams was defi
nitively shown to proceed in the mode of multiple scattering.
