Optical Model Analysis of the 16O+16O Nuclear Scattering Reaction around ELAB=5MeV/Nucleon1
Abstract
In this study, the experimental data on elastic scattering of 16O +16O reaction at the incident energies ELAB=75.0, 80.6 and 87.2MeV have been analyzed theoretically within the framework of the Optical model formalism by using the Fresco code. Our cross-section calculations have revealed a good agreement with the experimental data as much as the previous theoretical works. It is suggested that, more suitable fits with the experimental data may be obtained in coupled-channels formalism by considering the absorption due to the 3- and 2+ channels.
