Abstract
We report a variational calculation of ground state energies and radii of H e-4(N) droplets (3 less than or equal to N less than or equal to 40), using the Aziz HFD-B (HE) atom-atom interaction. The trial wave function has a s imple structure, combining two-and three-body correlation functions coming from a translationally invariant configuration-interaction description, and Jastrow-type short-range correlations. The calculated ground state energie s differ by around 2% from the diffusion Monte Carlo results. [S0163-1829(9 9)07333-6].
