Abstract
An analytical model, recently developed to study the electromagnetic dissociation (EMD) energy spectra of two-neutron halo nuclei, is applied to 11-Li and 14-Be. We find that a reliable set of experimental data on EMD could help to resolve the problem concerning the structure of the 11-Li ground state. For 14-Be we find a mutual inconsistency between the existing experimental data on the binding energy, radius and EMD energy spectrum. We also conclude that the structure of 14-Be is essentially more complicated than the structure of other Borromean two--neutron halo nuclei.
