We present a semiclassical and mostly analytical model of elastic neutron
breakup reactions for exotic projectiles. Both nuclear and Coulomb induced
reactions are considered and the potentials are treated to all orders in the
interactions. Furthermore we introduce a technique which allows the use of the
full Coulomb potential, thus including all multipoles besides the dipole.
Results for deeply bound states as well as for halo initial states are
presented and it is shown that experiments on heavy targets would be well
suited to study exotic nuclei with tightly bound valence nucleons.Comment: 10 pages, 17 figures. Accepted for publication in Nuclear Physics
