The small deviations between the measured and theoretical Fresnel reflectivity for an ideally sharp flat interface for wave-vector transfer $$\lesssim$$0.5 Å$$^{-1}$$ imply an interfacial width for the electron density profile of $$\lesssim$$1.3$$\pm$$0.2 Å. This is consistent with a model of atomic close packing which lacks structure along the surface normal at length scales >10 Å.
