The polarization in neutron-proton scattering at 29.6 MeV was deduced from asymmetries measured at every 10' c.m. from 50 to 150' c.m. The incident neutron beam was derived from a high-pressure deuterium gas cell via the 'H(d, n)'He reaction at 37' c.m. The beam passed through a spin rotation magnet and, at the target location 5.4 rn from the gas cell, possessed a flux of 5 )& 10' n/sec and a polarization of 0.32~0.04. Data between 50 and 110' c.m. were obtained using scintillating CH target in coincidence with neutron detectors, while data between 120 and 150' c.m. were obtained using recoil protons from a CH2 target. Total errors in the derived polarizations ranged from~0.007 to~0.022. These data agree very well with three previous values measured near 30 MeV at Los Alamos, but they disagree with Harwell data indicating small or negative polarizations near 150' c.m. The present results agree well with predictions of the Livermore X and Yale IV phase shift sets, but slightly favor the former.
