Calculations of Ground-State Properties of LiquidHe4Droplets

Quantum mechanical calculations of the ground states of droplets of $N$ atoms of ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ are reported. The calculations have been made by the variational Monte Carlo method for $4<~N<~728$ and by the Green's function Monte Carlo method for $3<~N<~112$. The energies, rms radii, and density distributions are reported; liquid-drop fits to the energies and radii are discussed.
