The 12C\(α,γ\)16O reaction is crucial for the understanding of He burning in massive stars, but the low-energy cross section is highly uncertain. To address this problem we have measured at sub-Coulomb energies total cross sections for the 12C\(6Li,d\)16O and 12C\(7Li,t\)16O reactions to the bound 2+ and 1- states of 16O. The data are analyzed to obtain the reduced α widths of these states. Together with capture and phase-shift data, these results provide for a more accurate determination of the low-energy 12C\(α,γ\)16O S factor: SE1\(0.3 MeV\) = 101+/-17 keV b and SE2\(0.3 MeV\) = 42+16-23 keV b for the E1 and E2 multipole components of the reaction.
