The polarization of protons following the ${\mathrm{O}}^{16}(d, p){\mathrm{O}}^{17*}$ (0.87 MeV) reaction ($l_n=0\mathrm{}$) has been measured over the angular range $15°<~{\theta }_p<~110°$ at $E_d=7, 8.2, \mathrm{and} 9.55$ MeV and at 15° and 30° at several energies in the range $6.5 \mathrm{MeV}<~E_d<~9.55 \mathrm{MeV}$. Large polarizations are observed which are practically independent of deuteron energy; this fact suggests that the polarization arises from a direct interaction mechanism. The results imply that spin-dependent distortions will be required in any distorted-wave stripping description of this reaction.
