Comparative study of the radius of sensitivity of the optical model potentials for Li6+Ni58,64 and O16+Ni58,64
Abstract
Radii of sensitivity were estimated for the Li6+Ni58,64 system at energies near the Coulomb barrier. For comparison purposes, such radii were also estimated for stable O16 scattered from the same target isotopes. The elastic scattering data were analyzed with folded real potential generated from DDM3Y nucleon-nucleon interaction and an imaginary potential of volume Woods-Saxon form. The most sensitive radii for the O16+Ni58,64 system are found to be energy independent and close to the strong absorption radius. For the Li6 projectile, unlike its strongly bound counterpart, the crossing radius increases with decreasing energy. However, no two crossing situation has been observed for either the Li6+Ni58,64 or the O16+Ni58,64 system at the top of the barrier.
