Measurement of the ²H(p, γ)³He S factor at 265-1094 keV

NUCLEAR REACTIONS ²H(p, γ)³He, E=400-1650 keV from the 3-MV Tandetron accelerator at Dresden; measured Eγ, Iγ using two HPGe detectors, one surrounded by BGO escape-suppression shield; deduced astrophysical S factors at 14 different incident proton energies, corrected for the assumed ab initio angular distributions of γ rays. ²H(p, γ)³He, E=1-1650 keV; analyzed S-factor data from the present experiment together with previous measurements in other energy regions, and compared with theoretical predictions. Relevance to deuterium abundance in big bang nucleosynthesis.
