    "abstract": "The J$^{\\pi}$=0$^+$ ground state of a drop of 8 neutrons and the lowest\n1/2$^-$ and 3/2$^-$ states of 7-neutron drops, all in an external well, are\ncomputed accurately with variational and Green\u0027s function Monte Carlo methods\nfor a Hamiltonian containing the Argonne $v_{18}$ two-nucleon and Urbana IX\nthree-nucleon potentials. These states are also calculated using Skyrme-type\nenergy-density functionals. Commonly used functionals overestimate the central\ndensity of these drops and the spin-orbit splitting of 7-neutron drops.\nImprovements in the functionals are suggested.",
