Deuteron Polarization in theBe9(p, d)Be8Reaction

The polarization of the deuterons from the ${\mathrm{Be}}^9(p, d){\mathrm{Be}}^8$ reaction was investigated at two angles, 30° and 90°, at an incident proton energy of 3 Mev. The deuteron polarization was measured by utilizing the asymmetry of the protons from the $\mathrm{D}(d, p){\mathrm{H}}^3$ reaction. The asymmetries were corrected for the finite geometry of the experiment. The analysis of the polarization from this data was performed employing a restricted set of interactions, and in this specific case the deuteron polarization was found to be + (11±5)% at 30°, and +(6+3)% at 90°. The sign of the polarization is in agreement with the semiclassical model, and the magnitude is less than the theoretical upper limit of 33%.
