High precision fusion data for O16+144Sm are analyzed in a coupled channels treatment which includes the excitation of the lowest 2+ and 3- states in both projectile and target. We find that certain higher-order couplings, which are often neglected in coupled channels analyses, play a significant role and improve the fit to the data. The nuclear potential which gives the best fit has a diffuseness of 0.64 fm. This is consistent with the prediction of folding models and also with the empirical expectation, based on analyses of elastic scattering data. © 1996 The American Physical Society.
