In order to study weakly-bound systems, such as halo nuclei, it is essential to take into account the unbound states of the system. Since these unbound states form a continuum of energies, their inclusion in reaction calculations requires the introduction of a discretization method, i.e., the representation of the continuum by a finite and discrete basis. Among the different discretization...

We present new data for the reaction 11Li+208Pb, recently measured at the radioactive nuclear beam facility in TRIUMF (Vancouver, Canada) at energies around the Coulomb barrier (Elab = 24.2 and 29.7 MeV). The halo nucleus of 11Li is composed by a core nucleus of 9Li and two loosely bound neutrons. Due to the weakly bound structure, this nucleus is easily polarizable. Thus, in the presence of...

Neutron-rich fission fragments accelerated to energies around the Coulomb barrier are used for studying the reaction mechanisms of fusion at HRIBF. Fusion excitation functions have been measured using neutron-rich radioactive 132Sn beams incident on Ca and Ni targets. Large sub-barrier fusion enhancement has been observed in the reaction with the 40Ca target. A previously measured fusion...

74. Fusion reactions and neutron transfer in collisions induced by Li isotopes on Sn targets

Recently experimental evidences have been observed concerning the enhancement of the sub-barrier fusion cross section due to neutron transfer, both in reaction with stable nuclei [1,2] and with weakly bound nuclei [3]. The enhancement seems to be related to the sign of the Q-value for neutron transfer. A new mechanism has been proposed [4] for the sub-barrier fusion of weakly bound nuclei, in...
