We have measured the sub-barrier fusion cross sections for ${}_{}{}^{16}{}_{}{}^{}$,17,18O on ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ and we present the data and the experimental method in detail. The data were analyzed with a one-dimensional potential barrier inversion model, a two-dimensional incoming wave boundary condition model, and a two-dimensional Wentzel-Kramers-Brillouin model. We find that a multidimensional model is necessary to describe the enhanced fusion cross sections in oxygen and the two-dimensional incoming wave boundary condition model suggests that a complete description of the fusion, inelastic, and elastic cross sections is possible.
