Universal aspects of Efimov states and light halo nuclei
Physical Review C, 1997•APS
The parametric region in the plane defined by the ratios of the energies of the subsystems
and the three-body ground state, in which Efimov states can exist, is determined. We use a
renormalizable model that guarantees the general validity of our results in the context of
short-range interactions. The experimental data for one-and two-neutron separation
energies, implies that among the halo nuclei candidates, only 20 C has a possible Efimov
state, with an estimated energy less than 14 KeV below the scattering threshold.

Abstract
The parametric region in the plane defined by the ratios of the energies of the subsystems and the three-body ground state, in which Efimov states can exist, is determined. We use a renormalizable model that guarantees the general validity of our results in the context of short-range interactions. The experimental data for one-and two-neutron separation energies, implies that among the halo nuclei candidates, only 20 C has a possible Efimov state, with an estimated energy less than 14 KeV below the scattering threshold.
