Abstract

Due to the importance of (_4^7)Be (α,γ) (_6^11)C capture reaction in nuclear and astrophysics physics, the present study not only introduces the obtained reaction, but its potential, cross section and reaction rate is also calculated. Finally, after the introduction and calculation of astrophysical S-factors, a quantity with energy less dependent into the cross-section in low energies range for primordial nucleosynthesis, astrophysical s-factor for the reaction in the energy range of 0MeV-10MeV about 0MeV-b - 0.14MeV-b was obtained. Then it was compared with the obtained experimental value by NACRE and obtained theoretical value by cluster potential model. alpha capture reaction, nucleosynthesis energies, AV18 potential, astrophysical S-factors
