Abstract
Correspondences are shown between semiclassical and quantum mechanical calculations that employ the same real potential. Comparisons are made to experimental scattering, complete fusion, and total reaction cross sections for $^{16}\mathrm{O}$+$^{208}\mathrm{Pb}$. The separate roles of rainbow and absorptive effects are shown. Deductions of the nuclear potential from fits to data clearly depend on the adopted sequence of data fitting procedures and the freedom given at each stage to the parameters of the chosen potential. It is this sequence that plays a large role in the inference of weak vs intermediate vs strong surface absorption. The sequence we choose implies intermediate surface absorption for this case. Parameter adjustments are explored for data fits that employ the proximity potential.NUCLEAR REACTIONS Classical, semiclassical, and quantum mechanical analysis for the system $^{16}\mathrm{O}$+$^{208}\mathrm{Pb}$. Elastic scattering, fusing, and all reactive collisions are treated and related to classical turning points for each $l$ wave.
