Isotopic differences in the fusion cross sections for 0+0, observed by Thomas, et al., are interpreted with a coupled-channel model. We find that most of the subbarrier enhancement of /sup 18/O+ /sup 16/O over /sup 16/O+ /sup 16/O is attributable to the excitation of the low 2/sup +/ state in /sup 18/O. However, the model predicts the enhancement to persist above the barrier, contrary to experimental findings.
