Query: Influence of the halo upon angular distributions for elastic scattering
  and breakup   The angular distributions for elastic scattering and breakup of halo nuclei
are analysed using a near-side/far-side decomposition within the framework of
the dynamical eikonal approximation. This analysis is performed for 11Be
impinging on Pb at 69 MeV/nucleon. These distributions exhibit very similar
features. In particular they are both near-side dominated, as expected from
Coulomb-dominated reactions. The general shape of these distributions is
sensitive mostly to the projectile-target interactions, but is also affected by
the extension of the halo. This suggests the elastic scattering not to be
affected by a loss of flux towards the breakup channel.
