The E1 and E2 components of the /sup 12/C(..cap alpha..,..gamma..) /sup 16/O S factor are investigated microscopically with a generator-coordinate calculation involving ..cap alpha..+ /sup 12/C/sub g.s./, ..cap alpha..+ /sup 12/C(2/sub 1//sup +/), p+ /sup 15/N/sub g.s./, and n+ /sup 15/O/sub g.s./ configurations. The theoretical capture cross sections towards the ground state and excited states are in semiquantitative agreement with experiment. Simple corrections to the microscopic expressions lead to good agreement with experimental data. The corrected model provides an S factor of 0.24 MeV b at the astrophysically important energy 0.3 MeV.
