The number of bound nuclides with between 2 and 120 protons is around 7,000, and extrapolations for drip-line positions and selected nuclear properties, including neutron separation energies relevant to astrophysical processes, are very consistent between the models used.

Despite being a complex many-body system, the atomic nucleus exhibits simple structures for certain ‘magic’ numbers of protons and neutrons. The calcium chain in particular is both unique and…
Intrinsic reflection asymmetry in atomic nuclei

It is demonstrated that many aspects of nuclear structure can be understood in terms of this nucleon-n nucleon interaction, without explicitly invoking three-nucleon forces.
Shape coexistence and the effective nucleon-nucleon interaction
