    "abstract": "We explore the evolution of the structure of the ground state of a nucleus\nwith two valence nucleons as the system approaches the two particle threshold.\nWe use a three-body model of $core+n+n$ where the core is deformed and allowed\nto excite. We find that both NN correlations and correlations due to\ndeformation/excitation of the core inhibit the formation of halos. Our results\nsuggest that it is unlikely to find halo nuclei on the dripline of deformed\nnuclei.",
