“…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.

Fusion and elastic scattering of ⁶Li + ⁵⁸Ni at low energies

Abstract. Sub-barrier fusion cross sections (σ f us ) for the 6 Li + 58 Ni system, obtained from the respective evaporation protons, are examined in the present work. With respect to expectations of a simple one-dimensional barrier penetration model, a large enhancement of the data is observed. Good consistency with equivalent data reported previously for similar systems is found. A comparison with total reaction cross sections (σ R ), deduced from elastic scattering measurements reported previously, indicates that σ f us is close to σ R within the measured energy range. To estimate the contribution of complete fusion (CF), an optical model analysis of the elastic scattering data is performed where CF is identified with the absorption in a short range volume potential. A surface polarization potential is added to the bare nuclear potential to simulate the effect of peripheral reactions. The results obtained indicate that other mechanisms different from CF may be dominant, especially in the lower energy region.

With the recent availability of state-of-the-art heavy-ion stable and radioactive beams, there has been a renew interest in the investigation of nuclear reactions with heavy ions. I first present the role of inelastic and transfer channel couplings in fusion reactions induced by stable heavy ions. Analysis of experimental fusion cross sections by using standard coupled-channel calculations is discussed. The role of multi-neutron transfer is investigated in the fusion process below the Coulomb barrier by analyzing 32 S+ 90,96 Zr as benchmark reactions. The enhancement of fusion cross sections for 32 S+ 96 Zr is well reproduced at sub-barrier energies by NTFus code calculations including the coupling of the neutron-transfer channels following the Zagrebaev semi-classical model. Similar effects for 40 Ca+ 90 Zr and 40 Ca+ 96 Zr fusion excitation functions are found. The breakup coupling in both the elastic scattering and in the fusion process induced by weakly bound stable projectiles is also shown to be crucial. In this lecture, full coupled-channel calculations of the fusion excitation functions are performed by using the breakup coupling for the more neutron-rich reaction and for the more weakly bound projectiles. I clearly demonstrate that Continuum-Discretized Coupled-Channel calculations are capable to reproduce the fusion enhancement from the breakup coupling in 6 Li+ 59 Co.
