摘要：

The first measurement of the elastic scattering of the halo nucleus Li-11 and its core Li-9 on Pb-208 at energies around the Coulomb barrier is presented. The Li-11 reaction showed a large cross section for the breakup channel, even at energies well below the barrier. The analysis of the Li-11 + Pb-208 scattering data in terms of the continuum-discretized coupled-channel calculations indicates that the effect of the coupling to the breakup channels produces a strong suppression of the elastic cross section at energies above and below the barrier. This effect is mainly due to the strong Coulomb coupling to the dipole states in the low-lying continuum of Li-11.
