Abstract
Angular distributions for elastic and inelastic transitions in + scattering have been measured at MeV. For the , , and members of the ground-state rotational band, the angular distributions exhibit pronounced backward peaking characteristic of an -cluster exchange mechanism. The analysis of the ground-state transition in the first-order elastic transfer model yields no satisfactory fit although microscopic cluster form factors and full recoil corrections are employed. A coupled channels calculation for the , , and transitions reveals very strong coupling effects, indicating that the coherent superposition of first-order optical model and distorted-wave Born-approximation amplitudes may not be an adequate model for these reactions.
