Abstract

The 16O(p,γ)17F reaction is an important reaction in CNO cycle and effective in the stellar revolution. The Cross Section and S-Factor calculated with using woods Saxon potential for bound levels including 5/2+( ground state) and 1/2+ (first excited state). The main portion of the total cross section for both final states is provided by E1 transitions from the incoming p wave to the bound 1d5/2 and 2s1/2 states. It is clear that contribution of S- Factor in the ground state because of deeply bound state and higher angular momentum lesser than the contribution of first excited state and the halo properties of the proton at 1/2+ state. By comparing our results with the previous results, a good agreement observed. S-Factor at zero Energy for states 5/2+ and 1/2+ calculated 0.3482 and 10.21 (keV.b), respectively. Also, we calculated reaction rate, which seen good agreement between our results and NACRE & CA88 data.
