The low-lying structure of $^{13}$Be has remained an enigma for decades.Despite numerous experimental and theoretical studies, large inconsistenciesremain. Being both unbound, and one neutron away from $^{14}$Be, the heaviestbound beryllium nucleus, $^{13}$Be is difficult to study through simplereactions with weak radioactive ion beams or more complex reactions withstable-ion beams. Here, we present the results of a study using the$^{12}$Be(d,p)$^{13}$Be reaction in inverse kinematics using a 9.5~MeV pernucleon $^{12}$Be beam from the ISAC-II facility. The solid deuteron target ofIRIS was used to achieve an increased areal thickness compared to conventionaldeuterated polyethylene targets. The Q-value spectrum below -4.4~MeV wasanalyzed using a Bayesian method with GEANT4 simulations. A three-point angulardistribution with the same Q-value gate was fit with a mixture of $s$- and$p$-wave, $s$- and $d$-wave, or pure $p$-wave transfer. The Q-value spectrumwas also compared with GEANT simulations obtained using the energies and widthsof states reported in four previous works. It was found that our results areincompatible with works that revealed a wide $5/2^+$ resonance but shows betteragreement with ones that reported a narrower width.
