We derive a unified description of the low-energy elastic, inelastic, neutron transfer, and fusion cross sections of systems involving two stable oxygen isotopes. Coupled channels equations with an incoming wave boundary condition are employed, as is the no-recoil approximation; the adiabatic approximation, which violates unitarity, is avoided. A calculation with phenomenologically determined O16 + O16 and O16-n potentials reproduces the measured cross sections within the limitations of the model. A possible error in the data analysis for O16 + O17 by Thomas et al. is pointed out.
