Elastic and inelastic scattering of 158 MeV 9Be ions

The elastic scattering of 158 MeV 9Be ions was measured for seven targets ranging in mass from 12 to 197. Inelastic data for exciting the lowest 2+ states of 12C, 26Mg and 60Ni were also obtained. The elastic data for 12C and 16O show pronounced structures at the most forward angles which are rapidly damped as the scattering angle increases. The distributions for 26Mg and 27Al show marked structure with significant odd-even differences that can be ascribed to quadrupole scattering from the 27Al ground state. The elastic data were analyzed using the optical model with both Woods-Saxon and folding-model potentials. The folded potentials are too strong and require renormalization; they do not give good fits to the data for the lighter targets. The inelastic data were compared to distorted-wave calculations.
