| Abstract | Angular distributions of the elastic, inelastic, and breakup cross sections of the halo nucleus Be11 on $^{197}Au$ 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 $^{11}Be$ 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 $^{11}Be$, and the reaction mechanism is sensitive to the entanglement of core and halo degrees of freedom in $^{11}Be$. |
