Figure 2

Dependence of the intensity of X-ray scattering from Vulcan on the concentration of tetrabromoethane (TBE) in the solvent. The intensity is relative to that in air. Blue circles, observed values of scattering intensities (mean ± S.D., n = 8–11). These values are normalized so that the value at 0% TBE coincides with the theoretical value (red curve). Red curve, theoretical values of scattering intensity when the electron density of carbon is 1100 mol/L. Blue curve, best-fit scattering curve when the electron density of the carbon has a Gaussian distribution (gray curve; 1000 ± 160 mol/L.).
