摘要
Common and Newton black films, which are the ultimate stage of thinning of soap films, are investigated by absolute x-ray reflectivity. The challenging and open problem concerning these two systems is the determination of the equilibrium thickness of the aqueous core. X-ray reflectivity provides very detailed and new information about their sandwich structure: The Newton black film appears much thinner than expected. As opposed to the common black film, it does not contain any aqueous core but only a hydration layer. In both cases the amphiphilic structure is the same.
