Using a hall accelerator to investigate d(d, n)3He and d(p, γ)3He reactions in the astrophysical energy region

Abstract

We present new results on astrophysical S-factors and cross sections for reactions dd → 3He + n(2.5MeV) and pd → 3He + γ (5.5MeV) in ultra-low energy ranges 2.3–6.2 keV and 8.3–10.1 keV, respectively. Experiments were performed with proton and neutron beams produced by a pulsed Hall accelerator (Nuclear Physics Institute, Tomsk) and deuterated polyethylene (CD2) and frozen heavy water (D2O) targets. Within measurement errors, our results are consistent with the literature’s experimental results on pd and dd reactions for the given energy ranges, where D2O or gaseous deuterium targets were used.
