We analyse the resonant break-up of halo nuclei including possible excitations of the core both in the structure of the halo nucleus and in the reaction dynamics. The structure of the halo nucleus is treated in the weak-coupling limit, assuming a particle+core model with core excitations. The bound and resonant states of this system are calculated as an expansion in a pseudo-state basis, for which we use a recent generalization of the Transformed Harmonic Oscillator basis. This basis is used within a distorted wave Born approximation reaction framework which includes possible excitations and deexcitations of the core during the collision. We apply this scheme to describe the resonant break-up of 11Be on 12C at 67 MeV/u. Comparing with the available experimental data from RIKEN [N. Fukuda et al., PRC 70, 054606 (2004)] we discuss the possibility of extracting spectroscopic information of 11Be resonances from the analysis of the break-up angular distributions.
