Abstract

We discuss continuum effects in the scattering of exotic nuclei, and more specifically on the ¹¹Be + ⁶⁴Zn scattering. ¹¹Be is a typical example of an exotic nucleus, with a low binding energy. Elastic, inelastic and breakup cross-sections of the ¹¹Be + ⁶⁴Zn system are computed in the Continuum Discretized Coupled Channel formalism, at energies near the Coulomb barrier. We show that converged cross-sections need high angular momenta as well as as large excitation energies in the wave functions of the projectile. Extensions to other systems are simulated by different collision energies, and by varying the binding energy of ¹¹Be.
