“…Also, the disagreement with the results of the Amorim paper mentioned before casts doubts on the quantitative results of [19], as a more recent study from the same group [33] suggests better agreement with the results presented here. This newer analysis is one of a few recent studies extending the trajectory of this excited state into the scattering region to explore the possibility of finding a resonance in the n-19 C scattering sector [33,34,35].…”

The universal properties and structure of halo nuclei composed of two neutrons (2n) and a core are investigated within an effective quantum mechanics framework. We construct an effective interaction potential that exploits the separation of scales in halo nuclei and treat the nucleus as an effective three-body system. The uncertainty from higher orders in the expansion is quantified through theoretical error bands. First, we investigate the possibility to observe excited Efimov states in 2n halo nuclei. Based on the experimental data, 20 C is the only halo nucleus candidate to possibly have an Efimov excited state, with an energy less than 7 keV below the scattering threshold. Second, we study the structure of 20 C and other 2n halo nuclei. In particular, we calculate their matter form factors, radii, and two-neutron opening angles. * Electronic address: canham@itkp.uni-bonn.de † Electronic address: hammer@itkp.uni-bonn.de

“…[59] have observed a strong enhancement 01013-p.6 of the n− 19 C elastic cross section. The result of this kind of study can be quite relevant also for the analysis of actual cold-atom experimental results, where the two-body interaction can be varied.…”

Abstract. Universal aspects of few-body systems will be reviewed motivated by recent interest in atomic and nuclear physics. The critical conditions for the existence of excited states in three-body systems with two-identical particles will be explored. In particular, we consider halo nuclei that can be modeled as three-body nuclear systems, with two halo neutrons and a core. In this context, we also discuss the low-energy neutron− 19 C elastic scattering, near the conditions for the appearance of an Efimov state.

“…The results are tabulated on page 2 in [9]. We notice that as the two body binding energy reaches around 140 keV, the second Efimov state has its energy less than that of the two body leading to an unstable state.…”
