The polarization and differential cross section for neutrons scattered from deuterium are measured at five laboratory angles (22 deg , 48 deg , 80 deg , 100 deg , and 150 deg ) for incident neutron energies of 0.5, 1.0, and 1.95 Mev. The neutrons were produced in the Li/sup 7/(p,n)Be/sup 7/ reaction. The partially polarized beam emitted at 51 deg was used first directly and then with the spins processed through 180 deg in the transverse field of an electromagnet in order to determine the asymmetry in the intensities after scattering from deuterium. The results at 0.5 and 1.0 Mev give zero polarization within 2-3%. At 1.95 Mev small positive polarizations up to 4% are observed. The differential cross sections measured are more peaked at large angles than in earlier work. These data are corapared with earlier calculations and a new phase-shift analysis of these measurements is made. (auth)
