Abstract
The differential cross section angular distributions for 99-MeV elastic scattering from , , , , , and have been measured for center-of-mass angles up to . The angular distributions show progressively less structure with increasing target mass which is characteristic of strongly absorbed particles. Phenomenological optical-model analyses with Woods-Saxon form factors exhibit both discrete and continuous ambiguities in the parameters which yield a good fit to the data. The dependence of several real central potential families and the effects of a surface absorption term have been investigated. A semimicroscopic single-folding potential based on an ()- cluster model for gave a good description of the data only after renormalization of the real potential by a factor of ∼0.5.
