Abstract

We present a total of 191 and 203 data points of the elastic neutron-protonspin correlation parameters Aookk and Aoosk, respectively. Both observables were measured in a large angular interval. The observable Aookk was measured from 0.312 to 1.10 GeV and Aoosk from 0.80 to 1.10 GeV. The SATURNE II polarized beam of free neutrons obtained from the break-up of polarized deuterons was scattered on the polarized Saclay frozen-spin proton target. The beam polarization was oriented either along the beam direction or sideways, the target polarization was oriented longitudinally. Data are compared with phase-shift analyses predictions and with the PSI, LAMPF and SATURNE II results. Present results provide an important contribution to any future theoretical or phenomenological analysis.
