Abstract
We have performed torsional oscillator measurements of 4He films adsorbed on porous gold and gold preplated with Ar, Ne, D2. HD, and H2. On all substrates, the superfluid response is similar. The thickness of the non-superfluid layer as function of the substrate, however, increases monotonically with the well depth of the atom-sub strate interaction potential.
