The n-p polarization at 126 Mev was measured between 33 and 82 deg c.m. by scattering a 41% polarized neutron beam from liquid hydrogen. The energy threshold and angle of scattering were determined by a range-threshold neutron counter. By the use of a conjugate counter to detect the recoil protons in coincidence with the scattered neutrons, the background rate was held to about 10%. Many systematic errors were eliminated by the use of precession magnets to reverse the sign of the neutron polarization. The maximum polarization was found to be 0.580 plus or minus 0.040 at 56 deg c.m. This maximum is higher than that obtained in any of the Yale phase-shift predictions.
