“…In this anomaly the strength of the imaginary potential increases as the incident energy decreases, at energies below the Coulomb barrier. For 6 Li projectiles, it has been shown that the threshold anomaly does not appear irrespective of whether it is incident on a heavy or light target [19,20,21,22,23,24,25,26,27,28]. As for 7 Li the conclusions seem to be different since it has been shown that the behaviour does depend on the mass of the target.…”

Abstract.Recently, experimental measurements of elastic scattering angular distributions for the system 7 Li+ 58 Ni at ten different energies around the Coulomb barrier were made by the Heavy-Ion Group. The measurements were made at the Tandem Van de Graaff Particle Accelerator Laboratory in the National Institute for Nuclear Research (ININ) in Mexico. In this work, preliminary elastic scattering angular distributions for five energies (E lab = 12.0, 12.5, 13.0, 13.5 and 14.22 MeV) are presented. The preliminary experimental data were analyzed using the São Paulo Optical Model Potential (SPP) which is based on a double-folding potential, reproducing very well these data. A comparison is made with old data reported back in 1973 and in 2012. Further analysis is in progress in order to fully understand this particular system, specially because 7 Li is known to be a weakly bound nucleus.

“…Absence of the usual threshold anomaly in the OP, in collisions induced by weakly bound nuclei both stable and radioactive has been observed also for other systems (e.g. [21][22][23][24][25]). The 6,7 Li+ 64 Zn elastic scattering data have been also analised within the CDCC approach.…”

The reaction dynamics of collisions involving halo or weakly bound nuclei, at energies around the Coulomb barrier, can be strongly affected by the structure of such nuclei. Very strong entrance channel effects have been observed on various reaction pocess such as, elastic scattering, fusion and direct reactions when comparing collision induced by the 6 He and 11 Be halo nuclei with the ones induced by their cores 4 He and 10 Be. Collisions induced by the stable weakly bound nuclei 6 Li, 7 Li show also some peculiarities in comparison to the ones induced by well bound nuclei; coupling with the break-up channel is in fact very important in reproducing low energy data. In this contribution an overview of our present understanding of the discussed topic will be given along with the discussion of some new preliminary results.

“…The study of fusion reactions is complicated by the fact that one may have important incomplete fusion (ICF) contributions, following breakup of the projectile, competing with complete fusion (CF). Here we will discuss the results of some experiments, performed at the Catania Tandem, concerning the study of elastic scattering and Heavy Residue (HR) production in the collisions 6,7 Li+ 64 Zn at different energies near the Coulomb barrier.…”

“…As an example, the presence of a repulsive polarisation potential associated with continuum coupling may destroy the usual threshold anomaly in the Optical Potential (OP) (See e.g. [5][6][7][8]). The study of fusion reactions is complicated by the fact that one may have important incomplete fusion (ICF) contributions, following breakup of the projectile, competing with complete fusion (CF).…”

Abstract. We measured elastic scattering angular distributions and cross sections for heavy residue production for the systems 6,7 Li+ 64 Zn at different energies around the Coulomb barrier. The elastic scattering angular distributions have been reproduced by optical model fits using a renormalized double folding potential for the real and imaginary parts. Absence of usual threshold anomaly in the optical potential was found. The excitation functions for heavy residue production were measured using an activation technique. Comparison with different calculations suggest that complete fusion is the dominant reaction mechanism above the barrier whereas, below the Coulomb barrier, incomplete fusion and transfer dominate.
