Do halos exist on the dripline of deformed nuclei

A study of the effect of deformation and pairing on the development of halo nuclei is presented. Exploratory three‐body core + n + n calculations show that both the NN interaction and the deformation/excitation of the core hinder the formation of the halo. Preliminary self‐consistent mean‐field calculations are used to search for regions in the nuclear chart where halos could potentially develop. These are also briefly discussed.
