Evidence for the Polarization ofB12Nuclei Produced in a (d, p) Reaction

Abstract

Evidence is presented that a lower limit for the polarization of ${\mathrm{B}}^{12}$ nuclei produced in the ($d, p$) reaction at 2.8 Mev is 17±5%. The sign of the polarization $P_R$ is in disagreement with the Newns model, and it is in agreement with a modified classical model. The sign of the proton polarization determined by Hillman and by Juveland and Jentschke is also in agreement with the modified classical model.
