“…6 we show the reduced total reaction cross sections for the 7 Be + 27 Al system and also for the stable weakly bound projectiles 6,7 Li, 9 Be, and the tightly bound 16 O with the same 27 Al target. Data are from [10,21,22,28,29]. We also show data for the 7 Be + 27 Al system obtained at higher energies than ours (E lab = 17, 19, and 21 MeV) [30].…”

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.

“…These two collisions have been studied experimentally [43][44][45], and theoretically in nonmicroscopic CDCC approaches [7,8]. We cover energies around the Coulomb barrier (E B ≈ 38.9 MeV for 9 Be+ 208 Pb, and E B ≈ 8.0 MeV for 9 Be+ 27 Al).…”

We use microscopic 9 Be wave functions defined in a α + α + n multicluster model to compute 9 Be+target scattering cross sections. The parameter sets describing 9 Be are generated in the spirit of the Stochastic Variational Method (SVM), and the optimal solution is obtained by superposing Slater determinants and by diagonalizing the Hamiltonian. The 9 Be three-body continuum is approximated by square-integral wave functions. The 9 Be microscopic wave functions are then used in a Continuum Discretized Coupled Channel (CDCC) calculation of 9 Be+ 208 Pb and of 9 Be+ 27 Al elastic scattering. Without any parameter fitting, we obtain a fair agreement with experiment. For a heavy target, the influence of 9 Be breakup is important, while it is weaker for light targets. This result confirms previous non-microscopic CDCC calculations. One of the main advantages of the microscopic CDCC is that it is based on nucleon-target interactions only; there is no adjustable parameter. The present work represents a first step towards more ambitious calculations involving heavier Be isotopes.
