    "abstract": "We exploit the possibility of new configurations in three-body halo nuclei -\nSamba type - (the neutron-core form a bound system) as a doorway to Borromean\nsystems. The nuclei $^{12}$Be, $^{15}$B, $^{23}$N and $^{27}$F are of such\nnature, in particular $^{23}$N with a half-life of 37.7 s and a halo radius of\n6.07 fm is an excellent example of Samba-halo configuration. The fusion below\nthe barrier of the Samba halo nuclei with heavy targets could reveal the so far\nelusive enhancement and a dominance of one-neutron over two-neutron transfers,\nin contrast to what was found recently for the Borromean halo nucleus $^6$He +\n$^{238}$U.",
