    (2011-01-01) Sitnik I.M.; Perdrisat C.F.; Tomasi-Gustafsson E.; Ball J.; Bimbot L.; Bisson Y.; Boivin M.; Borzunov Y.T.; Boyard J.L.; Courtat P.; Gacougnolle R.; Garçon M.; Golovanov L.B.; Hennino T.; Jones M.K.; Kunne R.; Malinina L.V.; Nedev S.; Piskunov N.M.; Punjabi V.; Sans J.L.; Skowron R.; Strokovsky E.A.; Yonnet J.
    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.

    Measurement of tensor polarization of deuterons from 3He→d+p breakup at momenta from 4.60 to 5.66 GeV/c
    (2011-09-19) Sitnik I.M.; Perdrisat C.F.; Tomasi-Gustafsson E.; Ball J.; Bimbot L.; Bisson Y.; Boivin M.; Borzunov Y.T.; Boyard J.L.; Courtat P.; Gacougnolle R.; Golovanov L.B.; Hennino T.; Jones M.K.; Kunne R.; Malinina L.V.; Nedev S.; Piskunov N.M.; Punjabi V.; Sans J.L.; Skowron R.; Strokovsky E.A.; Yonnet J.
    The tensor polarization ρ20 of deuterons emitted in the 1H(3He,d↔)Χ 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 κ of the deuteron in 3He from 0 up to 0.4 GeV/c. The data obtained are compared with theoretical predictions. © 2011 American Physical Society.
