The absolute small-angle x-ray intensities, scattered by two activated carbons, are analyzed assuming that coals scatter as polydisperse distributions of uncorrelated layered cubic particles. The specific interphase surface areas and the densities of the samples are obtained by the particle populations resulting from the intensity best-fits. The values agree, within a factor two, with those obtained by different experimental techniques.

Abstract
The absolute small-angle x-ray intensities, scattered by two activated carbons, are analyzed assuming that coals scatter as polydisperse distributions of uncorrelated layered cubic particles. The specific interphase surface areas and the densities of the samples are obtained by the particle populations resulting from the intensity best-fits. The values agree, within a factor two, with those obtained by different experimental techniques.
