Abstract

We present the results of further optical-model analyses of data for the scattering of 16O at EA = 94 MeV. In particular, we explored the use of real potential shapes more general than the Woods-Saxon or folded ones. Evidence was found that fits to the 16O+12C data were sensitive to the real potential even at small radii and involved potentials with relatively weak absorption (S-wave S-matrix elements with z.sfnc;S0| ≈ 0.1). Significant modifications to the DDM3Y folded potential were required for the best fits to these data. The optimum potentials are represented well by a conventional Woods-Saxon potential with a real depth of 80 MeV. The more general shapes did not improve the agreement with the data for heavier targets.
