A "hybrid" R-matrix-optical model parametrization of the ^(12)C(α, γ)^(16)O cross section

Creators

Abstract

The ^(12)C(α,γ)^(16)O cross section at astrophysical energies has been determined from existing ^(12)C(α, α)^(12)C and ^(12)C(α,γ)^(16)O 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.
