The polarization of the neutrons produced by photodisintegration of deuterium by 2.75-Mev gamma rays has been measured and the results compared to theoretical predictions. The photoneutrons were taken at five gamma-ray- neutron angles between 45° and 135° in the laboratory and scattered from magnesium which has a broad resonance at these neutron energies. The 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 are found to be in agreement with the theory within experimental error.
