The pair-distribution function g2(r1,r2) in drops of liquid He4 is studied with the variational Monte Carlo method. It is shown that in drops having 70 or more atoms it can be approximated as a functional of the local one-particle density and the separation r12. Energy-density functionals based on this approximation of g2 give a fairly accurate description of the ground-state properties of the drops.
