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

... ve 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. PACS numbers: 25.70.Bc, 25.70.Mn, 25.60.-t I.
