We have measured the spin-transfer parameters KLL, KSL, KLS, and KSS at 788 MeV from 47° to 177° c.m., and also uncovered a 1016 % normalization discrepancy which affects all previous np elastic spin data from LAMPF. Results disagree significantly from previous phase-shift predictions. With the inclusion of these new data the NN phase shifts and amplitudes (isospin 0 and 1) become well determined for the first time near 800 MeV. © 1991 The American Physical Society.
