Poves The nucleus 32 Mg sits within the so-called island of inversion. In simplest terms, the 32 Mg ground state (nominally a closed neutron, N = 20 , shell) is dominated by components involving neutrons excited to the next higher, p f shell. Extended shell-model calculations show that particle-hole states (0p0h, 2p2h, and 4p4h) are important. The present work demonstrates that 30 Mg( t , p ) 32 Mg two-neutron transfer cross sections to the first two 0 + states can be understood in a simple three-state mixing model. [Phys. Rev.
