Comment on ‘‘Simultaneous analyses of elastic scattering and fusion cross sections for theS32+58,64Ni systems at energies near the Coulomb barrier’’

An explanation is offered for the large fusion radii obtained in the optical model description of heavy-ion fusion given by Udagawa {ital et} {ital al}. An extension of the model is suggested, and possible effects on the spin distribution are discussed. It is contended that the large fusion radii {ital cannot} be deduced from the elastic scattering alone. The role of Coulomb excitation for these systems is also discussed.
