Differential cross section for neutron-proton radiative capture at En=63.4 MeV

Bibliography: pages 120-128.The angular distribution of photons from n-p radiative capture of 63.4 MeV neutrons has been measured using a new technique in which both the photon and the deuteron were detected simultaneously and the deuteron identified using pulse shape discrimination. Data taken at eight n-ϒ angles (45°-150°) were transformed to deuteron photodisintegration cross sections at the equivalent laboratory energy, Eᵧ = 33.9 MeV. The data were analysed in combination with independent measurements of the 0° and 180° cross sections. Legendre polynomial coefficients obtained from the analysis are consistent with other measurements in this energy range as well as with values reported from global fits. The measurements deviate marginally from predictions based on potential model calculations using the Bonn r-space and Paris potentials
