Abstract.
Green's function Monte Carlo methods are used to provide benchmarks for studies of low-density neutron matter. The zero-temperature equation of state and pair correlation functions are studied for the AV8\(^\prime\) NN interaction model, and for an idealized model comprised of neutrons with a short-range interaction and an arbitrarily large (negative) scattering length. For this idealized problem the equation of state is a constant multiplied by the Fermi-gas energy, this constant is found to be nearly 1/2. Similar ratios are found for realistic NN interactions.
