New measurements of the ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$($d$,$p$) reaction cross sections to the ground-, 0.87-, and 5.09-MeV states in ${}_{}{}^{17}{}_{}{}^{}\mathrm{O}$ have been performed for eleven angles from 17.5° to 150° at a bombarding energy of 12 MeV. The results are compared with earlier measurements at the same energy. The new measurements are shown to resolve a discrepancy observed for the comparison of the neutron strength of the unbound 5.09-MeV state extracted from earlier ($d$,$p$) studies with that from neutron scattering experiments. These results indicate that the method of Vincent and Fortune for distorted-wave analysis of stripping to unbound states yields a reliable value for the neutron width for this important test case. Measurements of ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$($d$,$d$) elastic scattering cross sections performed simultaneously are reported.
