Few-body universality in the deuteron- α system
Few-body universality in the deuteron- α system
We treat 6Li as an effective three-body (n−p−α) system and compute the d−αS-wave scattering length and three-body separation energy of 6Li for a wide variety of nucleon-nucleon and α-nucleon potentials which have the same (or nearly the same) phase shifts. The Coulomb interaction in the p−α subsyste...

We treat 6Li as an effective three-body (n−p−α) system and compute the d−αS-wave scattering length and three-body separation energy of 6Li for a wide variety of nucleon-nucleon and α-nucleon potentials which have the same (or nearly the same) phase shifts. The Coulomb interaction in the p−α subsystem is omitted. The results of all calculations lie on a one-parameter curve in the plane defined by the d−αS-wave scattering length and the amount by which 6Li is bound with respect to the n−p−α threshold. We argue that these aspects of the n−p−α system can be understood using few-body universality and that 6Li can thus usefully be thought of as a two-nucleon halo nucleus. |
