The Effect of Pressure on the Intensity of X-Rays Scattered from Nitrogen at Small Angles

Abstract

It is found that at small angles the scattering from a "permanent" gas diminishes due to intermolecular interference. The scattering cruves at various pressures closely resemble those of a liquid or solid. It is concluded that this is due to the closeness of the scattering centers rather than to any preferred orientation of molecular groups since it is unlikely that such groups would be present in a gas so far from the liquid state.
