We study the correlations between two neutrons in borromian nuclei {sup 11}Li and {sup 6}He by using a three-body model with a density-dependent contact two-body interaction. It is shown that the two neutrons show a compact bound feature at the nuclear surface due to the mixing of single particle states of different parity. We study the Coulomb breakup cross sections of {sup 11}Li and {sup 6}He using the same three-body model. We show that the concentration of the B(E1) strength near the threshold can be well reproduced with this model as a typical nature of the halo nuclei. The energy distributions of two emitted neutrons from dipole excitations are also studied using the correlated wave functions of dipole excitations.
