The polarization of protons from the ${\mathrm{Be}}^9(d, p){\mathrm{Be}}^{10}$ reaction has been measured at an incident deuteron energy of 10 MeV. The measurement has been carried from 13°(lab) to 80°(lab). The polarization is positive at forward angles but changes sign at about 70°(lab). Elastic scattering of protons from helium and carbon was used as the analyzing reaction. The axis of quantization is taken as $\mathrm{n}={\mathrm{k}}_d\times {\mathrm{k}}_p$.
