Neutron-deuteron analyzing power measurements at 50 MeV. I. Backward angles

The analyzing power of polarized 50 MeV neutrons on deuterons has been measured for center-of-mass angles between 90\ifmmode^\circ\else\textdegree\fi{} and 150\ifmmode^\circ\else\textdegree\fi{}. The data, combined with forward angle measurements, are compared with recent $\stackrel{\ensuremath{\rightarrow}}{p}+d$ analyzing power measurements at 49.3 MeV and also with a three-body calculation at 46.3 MeV.
