We have analyzed twenty elastic scattering angular distributions of the {sup 16}O+{sup 12}C system, measured at Sao Paulo Pelletron Laboratory and also data from the literature. The energies cover the region around and above Coulomb barrier, ranging from 8.54 up to 75.43 MeV in the center of mass reference frame. In the {sup 16}O+{sup 12}C scattering, two different processes can occur which result in same exit channel, the elastic scattering and the exchange of an alpha particle between projectile and target. We have used the Optical Model formalism for the elastic scattering and the DWBA to describe the alpha transfer reaction contribution. Thus, by analyzing the {sup 16}O+C elastic scattering at backward angles we have obtained the {sup 16}O{sub gs} alpha spectroscopic factor.
