Selected Topics of the Few-Nucleon Research Program at TUNL
Results of kinematically-complete cross-section measurements of the n — d breakup reaction at E n = 13 MeV are reported. The new data for the space-star configuration of the three outgoing nucleons are in good agreement with previous data but are considerably different from rigorous n — d calculations. A status report on our n — n and n — p FSI measurements is given. New information about the importance of three-nucleon force effects in the n — d reaction is expected from these data. New data for the analyzing power in n — p scattering at E n = 12 MeV are presented. The preliminary analysis of these accurate data does not support the small value obtained by the Nijmegen group for the charged πN N coupling constant.
