Measurement of tensor polarization of deuterons from 3He→d+p breakup at momenta from 4.60 to 5.66 GeV/c

Abstract : The tensor polarization ρ20 of deuterons emitted in the 1H(3He,d↔)X reaction at 0∘ in the laboratory system was measured at the Saturne National Laboratory in Saclay using the SPES-4 spectrometer with the HYPOM polarimeter located downstream from 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 in 3He from 0 up to 0.4 GeV/c. The data obtained are compared with theoretical predictions.
