INVERSION POTENTIALS DESCRIBING ELASTIC-SCATTERING OF C-12 NUCLEI AT E-CM = 11.254 AND 13.032 MEV

Fixed-energy quantum inversion of phase shifts corresponding to elasti c scattering of carbon nuclei at E-c.m. = 11.254 and 13.032 MeV is per formed to get model independent potentials. Phase shifts belonging to even angular momenta have been used as input data. The inversion poten tial is in general smooth and real in the outer (10 - 12 fm less than or similar to r) and inner (r less than or similar to 3 - 3.5 fm) regi ons, between which it exhibits complex oscillations and a Pauli core. These characteristic features of the inversion potentials need further investigations in light of existing nuclear models.
