The polarization of neutrons photoproduced from deuterium at about 148 degrees in the center of mass system was measured in the photon energy range of 11.0-22.9 Mev. The neutron polarization was analyzed in a low pressure helium diffusion cloud chamber by scattering the neutrons and observing the left-right asymmetry in the helium gas nuclear recoils achieved by photographing the individual recoils on film. Measurements were made on the stereoscopically projected recoil track images, and the data subjected to a maximum likelihood calculation. The polarizations measured in 4 photon energy intervals of 11.0-12.9 Mev, 13.0-15.9, Mev, 16.017.9 Mev and 18.0-22.9 Mev are -0.032 + or -0.078, -0.198 + or -0.086, -0.25 + or -0.12, and -0.296 + or 1 0.137, respectively. The polarization is defined as positive in the directions of the incoming photon and outgoing photoneutron. (Author).

The polarization of the neutrons produced by photodisintegration of deuterium by 2.75-Mev gamma rays was measured and the results compared to theoretical predictions. The photoneutrons were tsken at five gamma-ray-neutron angles between 45 and 135 deg in the laboratory and scattered from magnesium which has a broad resonance at these neutron energies. Tne polarization was determined from the asymmetry in the left-right scattering from magnesium. The neutrons are found to be negatively polarized as predicted. The magnitude of the polarization and the dependence on the gamma-ray-neutron angle were found to be in agreement with the theory within experimental error. (auth).
