Neutron-proton radiative capture at 14.4 MeV

Abstract The energy spectrum of deuterons from the H(n, d)γ reaction at 14.4 MeV was measured with a counter telescope. The c.m. differential cross section of this reaction was deduced from the deuteron energy distribution. A least-squares fit yielded a total cross section of σ = 30.6±1.8 μb, which is about 10% larger than the theoretical prediction. The isotropy ratio a b was found to be 0.08±0.06 and the asymmetry parameter was determined to be d b = 0.12±0.09 .
