Coulomb break-up of halo nuclei within an adiabatic model

We investigate the Coulomb dissociation of halo nuclei, assuming that the excitation of the projectile is to states in the low-energy continuum. The method used retains all finite-range effects associated with the interactions between the break-up fragments and can use realistic wavefunctions for the halo nuclei. We apply the method to Coulomb break-up of 6He and 19C on heavy targets, at incident energies below 100 MeV/nucleon, for calculations of alpha particle energy distributions and parallel momentum distributions of 18C, respectively. The absolute magnitudes of the energy distributions and the widths of the parallel momentum distributions are sensitive to the assumed structures of the halo nuclei. (author)
