Abstract:	The adsorption of⁴He films for coverages from1/4 to3 monolayers ona H₂ surface at low temperatures is studied with Path Integral Monte Carlo. We calculate the binding energy per⁴He atom to the substrate, density profiles of⁴He and H₂, zero point motion of⁴He and H₂, and the superfluid density of⁴He.
