The surface peaked modification to the conventional six-parameter representation of an ..cap alpha.. particle-nucleus interaction potential has been studied further. In particular we have used a nucleon-nucleus optical potential folded over the ..cap alpha.. particle to derive the central well depth, and it is found that constant geometry parameters can be used to fit the A dependence and energy dependence of the optical model for /sup 9/0Zr from 40--140 MeV. It is further found that good quality fits to elastic scattering can be obtained for the entire energy range for /sup 9/0Zr with constant geometry for the Woods-Saxon imaginary well depth, resulting in a five search parameter potential. The energy dependence can be incorporated in the strengths of the real and imaginary components of the potential and the geometrical parameters of the modification.
