Numerical study of transition rate and B(E2) transition strengths for 17O(p,γ)18F reaction

The study of the astrophysical S-factor is one of the methods of analyzing proton radiation capture reactions in the theoretical framework for low temperatures. In this research, we have numerically studied the proton radiative capture reaction by 17O using the Woods-Saxon potential model. First, the astrophysical S-factor reaction was calculated at low energies, and then the reaction rate of was obtained from the astrophysical S-factor. Also, in this study, the electrical quadrupole transition strength (B[E2]) for excited states 18F nucleus has been calculated. We found that B[E2] depends on the energy and spin of the excited states. The results corresponding to the astrophysical S-factor, reaction rate and transition strength at energy range of 200-500 keV were compared with experimental data and other theoretical models and were in good agreement. Also, the astrophysical S-factor at zero energy was calculated by the extrapolation method for (5/2)+ state and S(0)=4/8 keV b.
