摘要

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.
