The triton angular distribution in the 12C(7Li,t)16O reaction has been measured at 20 MeV incident energy. Comparison of the data with Finite Range DWBA and CDCC-CRC calculations show that breakup coupling effects are prominent in the transfer to the ground state. This observation is similar to that in the 12C(6Li,d) reaction at the same incident energy. The alpha spectroscopic factor of the 16O ground state is determined (Sα=0.25) from a comparison of the measured angular distribution with respect to the CDCC-CRC calculations. The E2 S-factor of the 12C(α,γ) reaction at 300 keV in the framework of a potential model is determined to be about 118 keV-barn.
