Abstract
The presence of low-lying 1 virtual state in the nLi system, when included in Faddeev three-body calculations, has a pronounced effect on the structure of the halo. The resulting momentum distributions, calculated in the Serber model, have a narrow width comparable with the experimental data. The structure of would then have nearly 50% of s-wave motion between the neutrons and the core. The three-body system may also approximately fulfill the conditions for the appearance of Efimov states, and there may exist low-lying excited states near the breakup threshold.
