IWBC ANALYSIS WITH QUASIMOLECULAR OPTICAL POTENTIALS

Abstract

The quasimolecular optical potential with Incoming Wave Boundary Condition model is used to obtain the fusion and elastic scattering cross-section at the sub-Coulomb region and above. This has been done for the 16 O +16 O and 12 C +12 C systems. It is found that sudden potentials describe well the average trend in the fusion and elastic scattering cross-section using the Incoming Wave Boundary Condition Method. Potentials fits for low energy are then used to obtain cross-sections at higher energies. Excellent agreement is obtained for the location of various peaks observed experimentally, especially in the case of 16 O +16 O . The parameters from these potentials give information on the nuclei in these dynamical situations. We find that a larger radius and a low density in the central region is required to explain the phenomena. The range of Yukawa potentials used are also larger by a factor of two as compared to those used by other authors.
