Representative work: A measurement of the $^{50}\mathrm{Ti}(d,p)^{51}\mathrm{Ti}$ reaction at 16 MeV was performed using the Super Enge Split-Pole Spectrograph to measure the magnitude of the $N=32$ subshell gap in Ti. Seven states were observed that had not been observed in previous $(d,p)$ measurements, and the $L$ transfer values for six previously measured states were either changed or measured for the first time. The results were used to determine single neutron energies for the ${p}_{3/2}$, ${p}_{1/2}$, and ${f}_{5/2}$ orbitals. The resulting single neutron energies in $^{51}\mathrm{Ti}$ confirm the existence of the $N=32$ gap in Ti. These single neutron energies and those from previous measurements in $^{ A measurement of the $^{54}\mathrm{Fe}(d,p)^{55}\mathrm{Fe}$ reaction at 16 MeV was performed using the Florida State University Super-Enge Split-Pole Spectrograph to determine single-neutron energies for the $2{p}_{3/2}, 2{p}_{1/2}, 1{f}_{5/2}, 1{g}_{9/2}$, and $2{d}_{5/2}$ orbits. Two states were observed that had not been observed in previous ($d,p$) measurements. In addition, we made angular momentum transfer, $L$, assignments to four states and changed $L$ assignments from previous ($d,p$) measurements for nine more states. The spin-orbit splitting between the $2{p}_{3/2}$ and $2{p}_{1/2}$ orbits is similar to that in the other $N=29$ isotones and not close to zero as a previous measure
