Abstract

The ¹²C(α, γ)¹⁶O reaction rate has been reevaluated using recently published cross section estimates. The results suggest that the temperature dependence of the reaction rate as given by Caughlan & Fowler should be revised, even though the absolute cross section of ¹²C(α, γ)¹⁶O still needs a better determination at low energies. Values for the stellar reaction rate of ¹²C(α, γ)¹⁶O have been calculated for a recommended cross section as well as for the experimental upper and lower limits of the cross section. In addition, analytic expressions for these reaction rates are given for 0.03 ≤ T₉ ≤ 2.
