Abstract

The angular distribution of the analyzing power in 2H(n,n2H elastic scattering has been measured at a neutron energy of 14.2 MeV in the angular range 50° to 152° c.m. Neutrons with a polarization of approximately 0.5 were obtained from the 3H(dn)4He reaction at a deuteron energy of 140 keV and lab emission angle of 82°. The 3H(dn)4He reaction was induced by vector polarized douterons obtained from a source of polarized ions. The latter was of a conventional “atomic beam” type. The results show good agreement with the data on the charge symmetric p+d process at a proton energy of 14.5 MeV. Comparison is also made with the theoretical calculations of Doleschall and of Pieper and a good agreement is found.
