Measurement was made of dsigma/dt for n/sub arrow-up/+p/sub arrow-up/..-->..n+p at P/sub perpendicular//sup 2/=0.8 and 1.0(GeV/c)/sup 2/ at 6 GeV/c. The 6-GeV/c 53%-polarized neutrons from the 12-GeV/c polarized deuteron beam at the Argonne zero-gradient synchroton were scattered from our 75%-polarized proton target. Both spins were oriented perpendicular to the scattering plane. We found large unexpected spin-spin effects in n-p elastic scattering which are quite different from the p-p spin-spin effects.
