Exotic light-nuclei with low particle separation energy can exhibit a very extended matter distribution, the so-called nuclear halo [1, 2]. At collision energies around the Coulomb barrier, the presence of a halo enhances the coupling between the elastic and reaction channels, such as breakup, transfer, and fusion, as compared to stable well-bound nuclei. The Coulomb barrier scattering of single-nucleon halo nuclei such as 8B (1p) and 15C (1n), or two-nucleon haloes such as 17Ne (2p) and 6He (2n), are particularly interesting, due to a complex interplay between nuclear and Coulomb forces and valence nucleon correlations on the dynamical couplings [3, 4, 5, 6]. In this contribution, the characteristic features of low-energy dynamics of nuclear haloes will be presented and discussed, making particular emphasis of latest experimental results and its interpretation in terms of coupled channel calculations.
