Abstract
Momentum distributions of particles from nuclear break-up of fast three-body halos are calculated consistently, and applied to Li. The same two-body interactions between the three particles are used to calculate the ground state structure and the final state of the reaction processes. We reproduce the available momentum distributions from Li fragmentation, together with the size and energy of Li, with a neutron-core relative state containing a -state admixture of 20\%-30\%. The available fragmentation data strongly suggest an -state in Li at about 50 keV, and indicate a -state around 500 keV.
