We report results of path integral Monte Carlo and density functional studies of 4He adsorption on a lithium substrate at low temperature. A recently proposed, accurate potential is used to model the 4He-substrate interaction. Results show evidence of continuous growth of a 4He film, with a superfluid monolayer at low coverage and no well-defined layering at higher coverages. Estimated superfluid transition temperatures exhibit a coverage dependence similar to that found in recent experiments of Csathy et al.
