Coupled-channels calculations are performed to predict fusion, elastic scattering, and inelastic scattering cross sections for the [sup 16]O+[sup 152,154]Sm and [sup 16]O+[sup 186]W systems at sub- and near-Coulomb barrier energies, taking into account the lowest rotational states of the target up to [ital I][sup [pi]]=8[sup +] explicitly. It is shown that experimental data of fusion cross sections taken recently with high precision, partial fusion cross sections, and also average spin values of compound nuclei formed after fusion are well reproduced by the calculations using optical potential parameters that can reproduce elastic and inelastic scattering data. The fusion-barrier distribution, defined as the second derivative of the fusion cross section [ital d][sup 2]([ital E][sigma])/[ital dE][sup 2], is also calculated and compared with experimental data. Particular attention is focused on effects of the [ital Y][sub 4] deformation of the target on various physical quantities.
