Abstract

The tensor polarization (ρ20) of deuterons emitted in the p(³He,d)X reaction at 0° in the lab. system was measured at the Saturne National Laboratory in Saclay, using the SPES-4 spectrometer with the HYPOM polarimeter in the area of its focal plane. The momentum of the detected deuterons was kept fixed at 3.77 GeV/c, while the momentum of the ³He beam was varied from 4.60 to 5.66 GeV/c, thus providing a range of internal momenta k of the deuteron inside the ³He from 0 up to 0.4 GeV/c. The obtained data are compared with the theoretical predictions.
