In this thesis, we used Effective Field Theory (EFT) to calculate the radiative ALPHA capture on 12C . This reaction is considered the “holy grail” in nuclear astrophysics because it determines the relevant abundance of 16O and 12C . We considered the E1 transition from initial p-wave at energy around the Gamow energy EG =0.3MeV.The theoretical formula for the cross section is obtained by fitting the EFT parameters to the phase shift and S-factor data. We find the Effective Range Expansion (ERE) parameters describing the ALPHA-wave phase shift are fine tuned. The shallow bound state and the resonance ALPHA-wave states are also described.
