We investigate the applicability of a random-matrix model to the description of noncollective excitations in heavy-ion reactions around the Coulomb barrier. To this end, we study fusion in the reaction 16O + 208Pb, taking account of the known noncollective excitations in the 208Pb nucleus. We show that the random-matrix model for the corresponding couplings reproduces reasonably well the exact calculations, obtained using empirical deformation parameters. This implies that the model may provide a powerful method for systems in which the noncollective couplings are not so well known.
