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