Exploring fusion at extreme sub barrier energies with weakly bound nuclei

Abstract

Results of measurement of residues formed in fusion of 6Li with 198Pt in the energy range of 0.68< E/$V_b$ <1.3 using a new sensitive off-beam technique are reported. The fusion excitation function and the derived average angular momenta do not indicate a change of slope at deep sub-barrier energies, contrary to recent observations. The present results for a system with weakly bound projectile confront the current understanding of the fusion hindrance at these low energies, underlying the role of internal re-organization on the dynamical path towards fusion.
