Direct reactions at intermediate energies are an important tool for studying the structure of weakly-bound exotic nuclei. The scattering of such nuclei has been successfully described using few-body models with the projectile assumed to consist of a: valence nucleon bound to an inert core which acts as a spectator during the reaction. However, there is evidence in the literature to suggest a collective excitation of the core is needed to explain the measured experimental partial breakup cross sections. In this thesis, the projectile is modelled as a set of coupled-channels eigenstates of a valence nucleon weakly-coupled to a quadrupole deformed rotational core. Using this model a new expression is derived for the diffractive breakup of the projectile to exclusive final core states within an eikonal framework. The interaction between the core and the target is described by a deformed core-target S matrix that can couple together different rotational core states and thus provide the potential for dynamic excitation of the core.
