Description
The Jπ=0+ ground state of a drop of 8 neutrons and the lowest 1/2- and 3/2- states of 7-neutron drops, all in an external well, are computed accurately with variational and Green close-quote s function Monte Carlo methods for a Hamiltonian containing the Argonne v18 two-nucleon and Urbana IX three-nucleon potentials. These states are also calculated using Skyrme-type energy-density functionals. Commonly used functionals overestimate the central density of these drops and the spin-orbit splitting of 7-neutron drops. Improvements in the functionals are suggested. copyright 1996 The American Physical Society
