Abstract
- Angular distributions of the elastic, inelastic, and breakup cross sections of the halo nucleus Be-11 on Au-197 were measured at energies below (E-lab = 31.9 MeV) and around (39.6 MeV) the Coulomb barrier. These three channels were unambiguously separated for the first time for reactions of Be-11 on a high-Z target at low energies. The experiment was performed at TRIUMF (Vancouver, Canada). The differential cross sections were compared with three different calculations: semiclassical, inert-core continuum-coupled-channels and continuum-coupled-channels ones with including core deformation. These results show conclusively that the elastic and inelastic differential cross sections can only be accounted for if core-excited admixtures are taken into account. The cross sections for these channels strongly depend on the B(E1) distribution in Be-11, and the reaction mechanism is sensitive to the entanglement of core and halo degrees of freedom in Be-11.
