The N=20 island of inversion is a section of the nuclear landscape centered around ³¹Na where significant structural changes have been observed. Except for a few cases most of the nuclei in this region have only been studied by their bound states. An experiment was performed at the National Superconducting Cyclotron Laboratory using the Modular Neutron Array and Sweeper dipole magnet to investigate neutron-unbound states of nuclei in this island of inversion. An 88 MeV/nucleon ³³Mg beam produced at the coupled-cyclotron facility was delivered to the experimental area and nuclei were populated via nucleon-removal reactions on Be targets. Using a proton removal from ³³Mg, states in ³²Na were populated. Because ³²Na is bound, its unbound excited states are studied using invariant mass spectroscopy by detecting the outgoing neutrons and residual ³¹Na from the decay and using their momenta to reconstruct decay energies. Preliminary results will be presented for this case.
