Neutron-deuteron studies in the energy range up to 50 MeV

At the Karlsruhe polarized neutron facility POLKA precise neutron-deuteron scattering experiments were carried out in the energy range from 18 to 50 MeV. Angular distributions of the n→-d analyzing power A/sub y/ were determined in ten energy bins for both the elastic scattering and the n→-d breakup to the FSI region. The data have been corrected for multiple scattering and finite geometry effects and are presented together with Faddeev calculations using various NN potentials. These calculations seem to be unable to reproduce the backward angle shape of recent dσ/dΩ data. The authors have, therefore, measured the differential cross section of the elastic and scattering in the angular range 1300-1700 (C.M.). The data were normalized to a measurement of the np cross section utilizing the same techniques of charged particle detection
