The Puzzle of the $^{\mathrm{13}}$Be

A considerable number of experiments have been performed to study the unbound nucleus $^{\mathrm{13}}$Be, however the energy and the ordering of its low-lying states remain unknown. Clarifying the low-lying structure of $^{\mathrm{13}}$Be will help in understanding the evolution of the N$=$8 shell gap and the nature of the nuclei near, or at, the neutron drip line. Additionally, the continuum structures of $^{\mathrm{13}}$Be are important for understanding the Borromean structure of the halo nucleus $^{\mathrm{14}}$Be. We performed the $^{\mathrm{12}}$Be(d,p)$^{\mathrm{13}}$Be transfer reaction in inverse kinematics at ISAC II, TRIUMF. The $^{\mathrm{12}}$Be beam at 9.5 MeV/u interacted with the IRIS solid D$_{\mathrm{2}}$ target, and recoils and ejectiles were detected in an annular silicon detector array. Preliminary analysis and results will be presented here.
