An analytical model, recently developed to study the electromagnetic dissociation (EMD) energy spectra of two-neutron halo nuclei, is applied to Li-11 and Be-14. We find that a reliable set of experimental data on EMD could help to resolve the problem concerning the structure of the Li-11 ground state. For Be-14 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 Be-14 is essentially more complicated than the structure of other Borromean two-neutron halo nuclei. (C) 2002 Elsevier Science B.V. All rights reserved.
