| Abstract: | 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 (∼ 2π 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 influence on the reaction dynamics. |
