摘要：

The nuclear-breakup and Coulomb-breakup contributions to the sequential breakup of 156-MeV Li-6 by Pb-208 via the 3+ resonance state of Li-6 at 2.186 MeV are investigated by three-body calculations based on the continuum-discretized coupled-channels method. The nuclear-breakup contribution is as important as the Coulomb-breakup one up to forward angles where the Coulomb breakup was believed to be dominant. The effects of multistep processes via various nonresonant continuum states due to the three-body dynamics are also found to be important.
