A target enriched to 40% in ${\mathrm{O}}^{17}$ was bombarded with 10-MeV deuterons, and the emitted protons were analyzed with a broad-range magnetic spectrograph. Angular distributions of the groups corresponding to the ground and 12 excited states of ${\mathrm{O}}^{18}$ were measured and analyzed using plane-wave theory. The predicted $3^{+}$ state arising from the ($d_{\frac{5}{2}}{s}_{\frac{1}{2}}$) configuration was found to be at 5.37-MeV excitation. Relative reduced widths and spectroscopic factors were determined from the stripping analysis, and were found to be in good agreement with recent theoretically predicted wave-function amplitudes. This implies that several states of ${\mathrm{O}}^{18}$ have an appreciable collective component.
