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

The tensor polarization {rho}{sub 20} of deuterons emitted in the {sup 1}H({sup 3}He,d)X reaction at 0 deg. 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 {sup 3}He beam was varied from 4.60 to 5.66 GeV/c, thus providing a range of internal momenta k of the deuteron in {sup 3}He from 0 up to 0.4 GeV/c. The data obtained are compared with theoretical predictions.
