摘要：
We investigate the three-body Coulomb breakup reaction of two-neutron halo nuclei Li-11, where we adopt the extended three-body model of Li-11 with paying attention to the pairing correlation of the nuclei, and also employ the complex scaling method (CSM) to solve the three-body unbound states of Li-11. From the results, we cannot find any dipole resonances, at least, having small decay widths. This means that the breakup strength is exhausted by the continuum states. We compare the obtained strength showing the low energy enhancement to the several experimental data.
