Abstract
Angular distributions have been measured for elastic scattering of + and + at MeV, covering an angular range up to , and for inelastic scattering of leading to the first , , and states in , and the first state in . The large angle cross sections () measured are an order of magnitude smaller than those reported earlier for scattering in this mass region. The data are analyzed in terms of the double-folding model with a realistic effective nucleon-nucleon interaction. The need to renormalize the effective interaction by a factor of ∼0.6 is removed when the strong projectile quadrupole effects are treated explicitly in coupled channels calculations. The inelastic cross sections are dominated by the imaginary part of the transition form factor, but the deformation lengths still agree well with the experimental values for the transitions studied.
