With large neutron-to-proton ratios far from the line of stability, nuclei develop exotic structures such as neutron skin and halo. Halo nuclei show unexpected behaviour, such as, large interaction cross section which in turn, points to large matter radius [1] and narrow momentum distribution of the valence neutrons. In this context, nuclei with two neutron halo are interesting systems to understand the correlation between the two halo neutrons and the core.
