Abstract
We link the structure of nuclei around , the heaviest doubly magic nucleus with equal neutron and proton numbers (), to nucleon-nucleon () and three-nucleon () forces constrained by data of few-nucleon systems. Our results indicate that is doubly magic, and we predict its quadrupole collectivity. We present precise computations of based on three-particle–two-hole excitations of , and we find that one interaction accurately reproduces the small splitting between the lowest and states.
