Abstract

The excitation function of He3(d, γ) capture radiation, measured from Ed=0.2 to 2.85 Mev, exhibits a broad resonance at 0.45±0.04 Mev, with a total cross section of 0.05±0.01 mb. Above this energy, the presence of nonresonant capture is observed. At Ed=0.58 Mev, the radiation is isotropic from 0° to 90° within ±10 percent. The measured gamma-ray energy of 16.6±0.2 Mev at resonance corresponds to a Q value for the He3(d, γ)Li5 reaction of 16.36±0.2 Mev. The experimental radiation width at resonance is calculated to be 11±2 ev, which is compared to the Weisskopf estimate for E1 transitions.
