Polarization inn−dScattering at 7.8 MeV

Asymmetries produced in the scattering of 7.8-MeV polarized neutrons have been measured to an accuracy better than ±0.020 for 12 angles ranging from 58° to 165° (c.m.). The ${}_{}{}^9{}_{}{}^{}\mathrm{Be}(\alpha , n_0)$ reaction was employed as a neutron source with a polarization of 0.539±0.012. The measured asymmetries agree with the 8-MeV data for the charge-symmetric $p-d$ scattering, indicating that the Coulomb effects are indeed small at this energy. The data also follow the trend of the 9-MeV calculation of Purrington and Gammel.
