| Abstract: | We apply the Green function Monte Carlo method to model ground states for the atomic nucleus 16O and for a droplet of eight 4He atoms assumed to obey Fermi statistics. Ground-state properties of the two systems are obtained by means of projection onto antisymmetric trial functions. The Monte Carlo process is stabilized by allowing the generation size to grow sufficiently fast. The variational method using refined backflow Jastrow-Slater wave functions is shown to be reasonably accurate. |
