S-factor of 14N(α,γ)18F reaction at low-energies

The astrophysical S-factor of the 14N(α,γ)18F reaction has been studied at range of bombarding energy 1-1.30 MeV. The 14N(α,γ)18F process is important in low energy astrophysics so that a possible source of energy in massive stars which have spent their hydrogen cycle. Using the Wood-saxon potential model, we have been calculated non resonances the astrophysical S-factors for the E2 transition and our results for Eα = 0.0  MeV is S ≈ 0.5  MeV.b where from experimental is measured to Eα = 0.0 is S ≈ o.7  MeV.b (Couch et al., 1971) that in comparison with our data good agreement is achieved for the astrophysical S-factor of this process.
