The $\beta$-decay of $^{31}$Ne

The neutron-rich Na isotopes approaching N=20 reside along the southern boundary of the “Island of Inversion”. These isotopes are of particular interest to nuclear structure, where observed details in the structure could lead to a deeper understand lying force which causes deformation in this mass region. Recently, the $\Beta$-decay of $^{31}$Ne has been studied, promising to add need structure detail to a region of the chart which had only been accessed using fast in-beam methods. Using the CCF at the NSCL, a $^{48}$Ca beam was fragmented, the fast $^{31}Ne$ isotopes were subsequently selected using the A1900 and implanted in the BCS, allowing event-by-event particle identification to be made. Excited states in the daughter $^{31,30}Na$ isotopes are identified by emitted $\gamma$-rays collected with 16 Clover-style HPGe and 15 LaBr$_3$ detectors surrounding the implant detector in a rhombicuboctahedron geometry and correlated to decay events. The ongoing analysis will be discussed, and preliminary results will be presented.
