SURFACE PROPERTIES OF LIQUID 3He AT ZERO PRESSURE

Abstract

Surface properties of quantum liquids have constituted a field for numerous interesting investigations, both experimental and theoretical. In this paper we study contribution of various nearest neighbours in simple cubic arrangement of the liquid helium toward the surface tension (σ) of liquid ³He. To this effect we use standard inter-atomic potential (Lennard Jones potential). We note that the major part of the contribution comes from its first four nearest neighbours. The agreement between our theoretical results with experimental values is satisfactory.
