ID BETAN, Rodolfo M. Cooper pair in the Borromean nucleus ¹¹Li. An. AFA [online]. 2016, vol.27, n.2, pp.53-55. ISSN 0327-358X.

Two free neutrons do not bound in the fre espace but they do in Borromean nuclei.The purpose of this proceedingis to investigate the neutron-neutron pairing in a Borromean nucleus ¹¹Liusing the continuum single particle level density.The partial-wave occupation probabilities are calculated as a function of the pairing strength. We found that the two neutrons become bound in the ⁹Li core for a very small value of the pairing strength (relative to the strength which gives the experimental energy of ¹¹Li).
