Differential cross section for n-p radiative capture at En = 63.4 MeV

Abstract

The angular distribution of photons from n-p radiative capture of 63.4 MeV neutrons has been measured. Data taken at eight n- γ laboratory angles (45°–150°) were transformed to deuteron photodisintegration cross sections at the equivalent laboratory energy, E γ = 33.9 MeV, and analysed in combination with independent measurements of the 0° and 180° cross sections. Legendre polynomial coefficients obtained from the analysis are consistent with values reported from global fits and deviate marginally from predictions based on the Bonn and Paris potentials.
