We present model results for the two-halo-neutron correlation functions, Cnn, for the dissociation process of light exotic nuclei modelled as two neutrons and a core. A minimum is predicted for Cnn as a function of the relative momentum of the two neutrons, pnn, due to the coherence of the neutrons in the halo and final state interaction. Studying the systems 14Be, 11Li, and 6He within this model, we show that the numerical asymptotic limit, Cnn\ensuremath→1, occurs only for pnn\ensuremath\gtrsim400\phantom\rule0.3em0exMeV/c, while such limit is reached for much lower values of pnn in an independent particle model as the one used in the analysis of recent experimental data. Our model is consistent with data once the experimental correlation function is appropriately normalized.
