Abstract
Fixed energy inverse scattering methods have been applied to extract {sup 12}C - {sup 208}Pb inversion potentials from measured differential cross sections. A semiclassical (WKB) inversion scheme was used to ascertain those complex, local interactions for the data taken at 1449 MeV. The first step was to fit the differential cross section data with a McIntyre form for the S-function. Then each McIntyre S-function was mapped into a rational function representation with which the inversion was performed. The inversion potentials vary significantly in their absorption components within the sensitive radial regions. The results highlight the crucial importance of making more extensive and accurate measurements of cross section data before a much further understanding can be made of heavy ion collisions. 18 refs., 3 tabs., 3 figs.
