    "abstract": "We present model results for the two-halo-neutron correlation functions,\n$C_{nn}$, for the dissociation process of light exotic nuclei modelled as two\nneutrons and a core. A minimum is predicted for $C_{nn}$ as a function of the\nrelative momentum of the two neutrons, $p_{nn}$, due to the coherence of the\nneutrons in the halo and final state interaction. Studying the systems\n$^{14}$Be, $^{11}$Li and $^{6}$He within this model, we show that the numerical\nasymptotic limit, $C_{nn}\\to 1$, occurs only for $p_{nn}\\gtrsim$ 400 MeV$/c$,\nwhile such limit is reached for much lower values of $p_{nn}$ in an independent\nparticle model as the one used in the analysis of recent experimental data. Our\nmodel is consistent with data once the experimental correlation function is\nappropriately normalized.",
