Reactions involving weakly bound stable projectiles

The effect of the breakup of weakly bound (stable or radioactive) nuclei on elastic and fusion cross sections is a subject of current experimental and theoretical interest. Although sub-barrier fusion involving strongly bound stable nuclei is well understood, there are contradictory results and predictions about the enhancement or suppression of the fusion cross section over predictions of the single fusion barrier, around the Coulomb barrier, when one of the collision partners is a weakly bound nucleus. The same is true for the energy dependence behaviour of the optical potential obtained from elastic scattering involving the above projectiles. A large alpha particle production in the reactions involving weakly bound projectiles is another interesting observation that needs detailed investigation for its origin. In this talk, the results obtained from the recent reaction studies involving weakly bound stable projectiles and the understanding of the underlying reaction mechanisms will be discussed.
