PHASE-SHIFT ANALYSIS AND INVERSION TO A POTENTIAL FOR C-12 + C-12 ELASTIC-SCATTERING AT ECM = 9.50 AND 11.38 MEV

In order to obtain optical potentials for the elastic scattering of heavy ions from experimental cross sections a two-step procedure is chosen. First, a phase shift analysis of measured angular distributions is carried out. Then, the inverse scattering problem at fixed energy is solved within the modified Newton method. This two-step procedure has been applied to the elastic scattering of C-12 on C-12 at incident energies of E(CM) = 9.50 and 11.38 MeV. Optical potentials for the C-12 + C-12 system are derived.
