The inelastic scattering of has been studied on targets of at 60 MeV, and at 56 MeV incident energy. Oxygen-16 ions emerging from the reactions were momentum analyzed in a split-pole magnetic spectrograph and identified in the focal plane by a position-sensitive ionization chamber. Angular distributions were extracted for transitions of multipolarity to final states with excitation energies below 5 MeV. In most cases single-channel distorted-wave Born approximation calculations fail to reproduce the data, the discrepancies tending to increase with higher multipolarity. Coupled-channels calculations that explicitly treat the strong couplings connecting all final states observed show improved, though not fully satisfactory, agreement with the data.
