Abstract

The E1 capture cross section for the reaction 12C(α,γ)16O to the 16O ground state has been measured for Ec.m.=1.29–3.00 MeV. A γ-ray–recoil-particle coincidence technique has been used to obtain essentially background-free reaction yields. A three-level R-matrix analysis of the E1 S factor leads to an allowed range for SE1 at 300 keV of 0.00–0.14 MeV b. A model-dependent R-matrix analysis and a hybrid R-matrix analysis result in values of 0.14 and 0.08 MeV b, respectively, for SE1(300).
