Query: Quasi-elastic barrier distribution as a tool for investigating unstable
  nuclei   The method of fusion barrier distribution has been widely used to interpret
the effect of nuclear structure on heavy-ion fusion reactions around the
Coulomb barrier. We discuss a similar, but less well known, barrier
distribution extracted from large-angle quasi-elastic scattering. We argue that
this method has several advantages over the fusion barrier distribution, and
offers an interesting tool for investigating unstable nuclei.
