英文摘要Quasielastic scattering and breakup angular distributions for the neutron halo nucleus Be-11 on a Pb-208 target at the laboratory energy of 210 MeV, which corresponds to 5.2 times the Coulomb barrier, were measured at HIRFL-RIBLL (Heavy-Ion Research Facility in Lanzhou and Radioactive Ion Beam Line in Lanzhou). The quasielastic scattering angular distribution of Be-11 shows an obvious suppression of the Coulomb nuclear interference peak (CNIP) even at such a high incident energy. Theoretical results with the continuum discretized coupled channels (CDCC) method are in correspondence with the experimental data. The measured angular distribution of the Be-10 fragments is well reproduced considering elastic breakup contribution with the CDCC calculations plus nonelastic breakup contribution with the model of Ichimura, Austern and Vincent [Phys. Rev. C 32,431 (1985)]. The reduced reaction cross section of the Be-11 + Pb-208 system was compared with those of other reaction systems including tightly and weakly bound projectiles impinging on medium and heavy mass targets, where the former shows a significant enhancement. Systematical comparisons between the experimental data and theoretical calculations suggest that elastic scattering with heavy targets (such as Pb-208) at relatively high incident energies is still sensitive to the structure of neutron-rich nuclei.
