Measurement of tensor polarization of deuterons from He-3 -> d plus p breakup at momenta from 4.60 to 5.66 GeV/c
Physical Review C
The tensor polarization rho(20) of deuterons emitted in the H-1(He-3, (d) over left right arrow )X reaction at 0 degrees 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 He-3 beam was varied from 4.60 to 5.66 GeV/c, thus providing a range of internal momenta k of the deuteron in He-3 from 0 up to 0.4 GeV/c. The data obtained are compared with theoretical predictions.
