Three-body Faddeev Calculation for 11Li with Separable Potentials

Abstract

The halo nucleus ${}^{11}$Li is treated as a three-body system consisting of an inert core of ${}^9$Li plus two valence neutrons. The Faddeev equations are solved using separable potentials to describe the two-body interactions, corresponding in the n-${}^9$Li subsystem to a p${}_{1/2}$ resonance plus a virtual s-wave state. The experimental ${}^{11}$Li energy is taken as input and the ${}^9$Li transverse momentum distribution in ${}^{11}$Li is studied.
