Abstract

The np and the pp analyzing powers Aoonod and spin correlations Aoonnd and Aooskd were measured simultaneously using the SATURNE II polarized deuteron beam at 0.744 and 0.794 GeV/nucleon. The results for the pp observables coincide with the free pp elastic scattering data. We thus can assume that also the np analyzing power Aoonod and spin correlations Aoonnd and Aooskd are equal to those for scattering of free polarized neutrons. The np data cover the angular region 95°⩽θCM⩽122°. Our results for Aoonod (np) confirm the phase-shift analysis predictions but spin correlations Aoonnd (np) and Aooskd (np) have never been measured in this energy region and will considerably affect the PSA solution. Present results allow conclusions about the angular dependence near the minimum of Aoono (np) and Aoonn (np) in the vicinity of 0.8 GeV.
