The scattering of the radioactive, weakly bound, halo nucleus 11Be from 209Bi has been studied at 40MeV beam energy. The measurement performed with a low-intensity and a large-emittance secondary beam could be made using an extremely compact, large solid angle (» 2¼ sr) detecting set-up, based on 8 highly segmented Si telescopes. The 11;9Be scattering angular distributions, as well as their relative reaction cross-sections, resulted to be rather similar. This may suggest that at Coulomb barrier energies the halo structure and the very small binding energy of the 11Be projectile have no big in°uence on the reaction dynamics
