摘要：

Coulomb breakup strengths of Li-11 into a three-body Li-9 + n + n system are studied in the complex scaling method. We decompose the transition strengths into the contributions from three-body resonances, two-body "Li-10 + n" and three-body "Li-9 + n + n" continuum states. In the calculated results, we cannot find the dipole resonances with a sharp decay width in Li-11. There is a low energy enhancement in the breakup strength, which is produced by both the two- and three-body continuum states. The enhancement given by the three-body continuum states is found to have a strong connection to the halo structure of Li-11. The calculated breakup strength distribution is compared with the experimental data from MSU, RIKEN and GSI. (C) 2003 Elsevier B.V. All rights reserved.
