A counter-telescope consisting of two proportional counters and a NaI scintillator in triple coincidence has been used to study the angular distribution of scattered deuterons and disintegration protons from the interaction of 14.1-Mev neutrons with deuterium. Charged reaction products were identified by simultaneous observation of particle energy and rate of energy loss. Thin radiators of deuterated and normal polyethylene were used, the latter to investigate the incident neutron spectrum and $n\ensuremath{-}p$ scattering at 14.1 Mev.The absolute differential cross sections observed over the recoil angular range 0 to 55 degrees in the laboratory for elastic $n\ensuremath{-}d$ and $n\ensuremath{-}p$ scattering are in good agreement with the recent nuclear-emulsion results of Allred, Armstrong, and Rosen, and with the theoretical results of Christian and Gammel. The anisotropy of $n\ensuremath{-}p$ scattering was found to be about six percent. Protons from disintegration of deuterium were observed over the angular range of 0 to 80 degrees in the laboratory, and the integrated cross section for the forward hemisphere is larger than has been observed previously. The energy distributions appear more nearly uniform than those estimated by Frank and Gammel, and the angular distribution more strongly peaked forward.
