COULOMB BREAKUP OF 2-NEUTRON HALO NUCLEI

We investigate the Coulomb dissociation of two-neutron halo nuclei, as suming that the excitation of the projectile is to states in the conti nuum with low energy. The method presented retains all finite-range ef fects associated with the interactions between the breakup fragments a nd can use realistic three-body wave functions for the two-neutron hal o nuclei. The method is applied to He-6, at incident energies below 10 0 MeV/nucleon, and calculations are compared with available data for t he alpha-particle energy spectrum following the breakup of He-6 on a h eavy target.
