“…It is also observed that the breakup channel slightly damps the so called Coulomb rainbow peak and increases the cross section at angles larger than the rainbow peak. The same qualitative effect has been recently observed in 6 He+ 58 Ni [15], 11 Li + 208 Pb [17] and 11 Be + 64 Zn [18] scattering. It also has been shown [32] that the damping of the Coulomb rainbow peak for the 8 B + 208 Pb, 58 Ni systems involving proton-halo projectiles is smaller than for the systems involving neutron-halo projectiles (like 11 Li and 6 He) because the dipole response of the 8 B is less.…”

“…Such nuclei are unstable by beta emission or electron capture, with relatively long lifetimes (milliseconds up to seconds), sufficient to produce a secondary beam. Light exotic nuclei usually present a pronounced cluster structure, with very low separation energies in comparison to their stable partners and can be found either in the neutron rich [9][10][11][12][13][14][15][16][17][18] or in the proton rich sides [19][20][21][22][23][24] of the nuclear chart. One of these nuclei is 8 B which is formed by a 7 Be core plus one proton bound by only 0.137 MeV to the core.…”

We present 8 B+ 27 Al elastic scattering angular distributions for the proton-halo nucleus 8 B at two energies above the Coulomb barrier, namely E lab = 15.3 MeV and 21.7 MeV. The experiments have been performed in the Radioactive Ion Beams in Brasil facility (RIBRAS) in São Paulo, and in the TwinSol facility at the University of Notre Dame, USA. The angular distributions were measured in the angular range of 15-80 degrees. Optical model and Continuum Discretized Coupled Channels calculations have been performed and the total reaction cross sections have been derived. A comparison of the 8 B+ 27 Al total reaction cross sections with similar systems including exotic, weakly and tightly bound projectiles impinging on the same target is presented.

Abstract. The present status of fusion reactions involving light (A < 20) radioactive projectiles at energies around the Coulomb barrier (E < 10 MeV per nucleon) is reviewed, emphasizing measurements made within the last decade. Data on elastic scattering (providing total reaction cross section information) and breakup channels for the involved systems, demonstrating the relationship between these and the fusion channel, are also reviewed. Similarities and differences in the behavior of fusion and total reaction cross section data concerning halo nuclei, weakly-bound but less exotic projectiles, and strongly-bound systems are discussed. One difference in the behavior of fusion excitation functions near the Coulomb barrier seems to emerge between neutron-halo and proton-halo systems. The role of charge has been investigated by comparing the fusion excitation functions, properly scaled, for different neutron-and proton-rich systems. Possible physical explanations for the observed differences are also reviewed.
