Paper Abstract

We present the results of an extensive study of X-ray reflectivities of dip lacquered and Au coated Al foils. The measurements are performed at four different energies from 0.71 keV to 8.1 keV. The foils span a range of fabrication parameters. We show, that two of three examined versions of a density variation model are able to explain the data. We fmd a strong dependence on the microroughness of thickness of the Au coating and of the Au deposition rates. We present data suggesting important correspondence between X-ray measurements and scanning tunneling microscopy measurements. We fmd no dependence on curing temperatures (70°C to 130°C). Finally, we have performed an energy scan of one of the foils, in the range 6 keV to 12 keV.
