We have measured the spin-transfer parameters {ital K}{sub {ital L}{ital L}}, {ital K}{sub {ital S}{ital L}}, {ital K}{sub {ital L}{ital S}}, and {ital K}{sub {ital S}{ital S}} at 788 MeV from 47{degree} to 177{degree} c.m., and also uncovered a 10--16 % normalization discrepancy which affects all previous {ital np} elastic spin data from LAMPF. Results disagree significantly from previous phase-shift predictions. With the inclusion of these new data the {ital NN} phase shifts and amplitudes (isospin 0 and 1) become well determined for the first time near 800 MeV.
