Low-energy neutron scattering on light nuclei and ${}^{19}$B as a ${}^{17}$B-$n$-$n$ three-body system in the unitary limit

Jaume Carbonell, Emiko Hiyama, Rimantas Lazauskas +1

We consider the evolution of the neutron-nucleus scattering length for the lightest nuclei. We show that, when increasing the number of neutrons in the target nucleus, the strong P…
