Few-body universality in the deuteron- system
Abstract
We treat 6Li as an effective three-body (n-p-α) system and compute the d-α S-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-α S-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.
