Abstract
A wavefunction for liquid He4 with a sufrace is constructed, and a variational calculation to minimize the additional surface energy gives an integro-differential equation for the function characterizing the surface. The surface structure can be determined in terms of bulk properties provided certain approximations are made for the density and pair correlation functions near the surface.Keywords
