Recent experimental data on elastic and inelastic scattering of approx. =180 MeV antiprotons from /sup 12/C, /sup 16/O, /sup 18/O, /sup 40/Ca, and /sup 208/Pb have been analyzed. The calculations have been performed by using the formulations based on a phenomenological model given by one of the authors in an earlier paper. It is found that the calculated differential cross sections for elastic and inelastic scattering and those measured experimentally in most cases are in very good agreement. Furthermore, the effective values of the equilibrium radius and surface thickness derived from the present analysis for each of the nuclei investigated as well as the estimated values of the C/sub lambda/ associated with the nuclear restoring force are very satisfactory. The results of the analysis also suggest that it is mainly the geometrical structure of the target nuclei which, in effect, determines the elastic and inelastic scattering cross sections for exciting the low-lying collective states.
