Abstrakt: We present the measurements of the spin correlation parameter A (np). A longitudinally polarized beam of free neutrons obtained from the break-up of polarized deuterons was scattered on the longitudinally polarized Saclay frozen-spin proton target. Measurements were carried out at SATURNE II, at neutron beam kinetic energies of 0.63, 0.88, 0.98 and 1.08 GeV. The data points cover the angular region from about 40° to 110° CM. The observed angular dependence of A (np) at 0.63 GeV agree with the phase shift analysis predictions except at small angles. [ABSTRACT FROM AUTHOR]
