Abstract

Liquid-vapour interface for a simple fluid modelled by the Lennard-Jones potential was treated by the first two mernbers of the Born-Green-Yvon-Bogolyubov hierarchy. The pair of coupled integral equations was solved numerically to get the density profile and the pair correlation function in the inhomogeneous region. It was found that one can get a significant result for the pair correlation function if the monotonous density profile is inserted in the equation determining the pair correlation function. On the other hand, we did not succeed in getting a convergentsolution for the density profile. This means that some further efforts will be necessary to overcome the difficulties connected with the unstable numerical procedures.
