Elastic and inelastic scattering of deuterons on 12C has been investigated in the incident energy range between 60 and 90 MeV. Angular distributions between 10° and 80° (lab) have been measured for states up to approximately 15 MeV; at still higher excitation energies some prominent groups of levels show up in the spectra, including a very broad structure peaked at 27 MeV. The elastic and inelastic scattering angular distributions were analyzed in the frame-work of standard optical model and coupled-channel analysis, respectively. The quadrupole deformation parameter was found to be β2 = -0.48 ± 0.02, independent of incident energy. The angular distributions for the second 0+ and first 3- state were analysed using a rotation-vibration coupling scheme.
