摘要：

The properties of liquid helium-4 are investigated in a mean-field approximation using a finite-range effective interaction. The long-range part (i.e., r>2.556 Å) coincides with the standard Lennard-Jones potential and the hard core is phenomenologically renormalized. The model reproduces the static polarizability of bulk liquid, as well as the actual surface energy of helium at zero temperature. The surface width is found to be 5.8 Å. A comparison is made with the earlier work of Ebner and Saam. © 1990 Plenum Publishing Corporation.
