Abstract: (APS)

We link the structure of nuclei around Sn100, the heaviest doubly magic nucleus with equal neutron and proton numbers (N=Z=50), to nucleon-nucleon (NN) and three-nucleon (NNN) forces constrained by data of few-nucleon systems. Our results indicate that Sn100 is doubly magic, and we predict its quadrupole collectivity. We present precise computations of Sn101 based on three-particle–two-hole excitations of Sn100, and we find that one interaction accurately reproduces the small splitting between the lowest Jπ=7/2+ and 5/2+ states.
