Abstract

The ¹²C(α,γ)¹⁶O cross section at astrophysical energies has been determined from existing ¹²C(α, α)¹²C and ¹²C(α,γ)¹⁶O data by means of a "hybrid" R-matrix - optical model method; we obtain an S-factor of 0.08 _-0.04^+0.05 MeV·b at E_c.m = 300 keV. The El γ-ray width of the 9.59 MeV state has been determined to be 23 ± 3 meV.
