MEASUREMENTS OF THE 2 AND 3 SPIN-INDEX OBSERVABLES IN NP ELASTIC-SCATTERING BETWEEN 0.80 AND 1.10 GEV

We present data of several rescattering observables measured in np ela stic scattering between 0.80 and 1.10 GeV. The SATURNE II polarized be am of free neutrons obtained from the break-up of polarized deuterons was scattered on the Saclay polarized frozen-spin proton, target. Thre e different configurations of beam and target polarization directions were used: the observables D(onon) and K(onno) were measured with the normal-normal spin configuration at eight energies; N(onkk), D(os'' ok ) and K(os'' ko) were determined with the longitudinal-longitudinal co nfiguration at six energies; N(onsk), D(os'' ok) and K(os'' so) with t he sideway-longitudinal configuration at six energies. Part of the dat a was obtained with an unpolarized CH2 target where only the two spin- index polarization transfer parameters K(os'' ko) and K(os'' so) were determined. Data are compared with phase shift analyses predictions an d with the LAMPF results at 0.788 GeV. Present results are the first m easurements of rescattering observables above 0.80 GeV. They provide a n important contribution to any future theoretical or phenomenological analysis.
