Full angular distributions for elastic and inelastic scattering of 11B on 58Ni have been measured at different bombarding energies around the Coulomb barrier. Measurement and analysis with coupled-channel calculationshave been performed for the first time for a system with the tightly bound 11B as projectile on a mediummass target. In these calculations, the real part of the interaction potential between nuclei was represented bya parameter-free double-folding potential. To avoid the use of an imaginary potential at the surface, severalinelastic transitions of the projectile and the target have been included in the coupling matrix. The result of thesecoupled-channel calculations are in very good agreement with all experimental angular distributions. The mostimportant result was the striking influence on the reaction mechanism of the ground-state-spin reorientation ofthe 11B nuclei.
