The spin-spin correlation parameters C{sub LL} and C{sub SL} were measured for np elastic scattering at the incident neutron kinetic energy of 634MeV. Good agreement was obtained with previously measured data. Additionally, the first measurement of the correlation parameter C{sub SS} was made at three energies, 484, 634, and 788 MeV. It was found that the new values, in general, do not agree well with phase shift predictions. A study was carried out to determine which of the isospin-O partial waves will be affected by this new data. It was found that the {sup 1}P{sub 1} partial wave will be affected significantly at all three measurement energies. At 634 and 788 MeV, the {sup 3}S{sub 1} phase shifts will also change.
