Structure effects in the elastic scattering for the 16O + 46,50Ti systems

Nuclear structure effects observed in the sub-Coulomb fusion of heavy-ions demand a careful investigation of the reaction cross section and optical potentials near the Coulomb barrier. The elastic scattering for the 16O + 46,50Ti systems was investigated in the bombarding energy range 30⩽Elab⩽70 MeV through an analysis using the São Paulo Potential. Experimental results suggest that there is no significant effect due to the differences in structure of the deformed 46Ti and the neutron magic 50Ti targets. This result is in agreement with the observation of no significant structure effects in the fusion cross section study for the same systems.
