We present a total of 191 and 203 data points of the elastic neutron-protonspin correlation parameters A_ookk and A_oosk , respectively. Both observables were measured in a large angular interval. The observable A_ookk was measured from 0.312 to 1.10 GeV and A_oosk 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.
