"Fusion, Break-up and Scattering of Weakly Bound Nuclei"


Abstract. The effect of the break-up of weakly bound nuclei on the fusion cross  section is a subject of major interest. The understanding of this  effect is important for the production of nuclei near the neutron drip  line and super-heavy nuclei. However, although there has been many  experimental and theoretical works in this field, at the present it is  still far from being understood. A full understanding of the fusion  and break-up processes induced by stable weakly bound  projectiles is  an essential step for the study of the fusion induced by  radioactive   beams. In order to have a comprehensive picture of this problem, one  has to study different energy regimes, from the sub-barrier to  above  barrier energies and also one has to span different nuclear masses, in  order to investigate the effect, on the fusion, of nuclear and Coulomb  break-ups. In this talk I will give an overall picture of our present  understanding of the field, based mostly on recent experiments  performed by our group and collaborators, on many different systems  involving fusion, breakup and scattering of  9Be, 6,7Li, 6He and  targets ranging from 27Al to 209Bi.
