Abstract
The breakup effect on the elastic scattering of by at MeV is investigated by the method of continuum-discretized coupled-channels (CDCC) based on the three-body model. The CDCC calculation well reproduces the experimental data of the elastic scattering, which is consistent with the result of recent studies based on the adiabatic three-body models. The breakup effect is significant and the coupling to the p-wave continuum states and the d-wave resonance state have a dominant contribution to the breakup effect. Dynamical polarization potential which simulates the breakup effect is evaluated and found to have a weakly repulsive real part and a long-range imaginary part of absorptive nature, characteristic of the weakly bound projectile with neutron halo.
