It has been realized that the interaction of the last valence protons and neutrons,in particular the monopole component of the residual interaction between those nucle-ons, can lead to significant shifts in the single-particle energies, leading to the collapseof classic shell closures and the appearance of new shell gaps. The “Island of Inversion”32around Mg, which is one of the most studied phenomena in the nuclear chart, is awell known example for such changes in nuclear structure.
