Abstract:

The structure of the neutron-halo in the ground state of 11Li is studied in the microscopic framework of the cluster-orbital shell model and the extended cluster model. Both of the models are understood to play a complementary role in gaining the correlation energies for the two types of relative motions between 9Li and the valence neutron and between the two neutrons. The lack of the binding energy of the cluster-orbital shell model is shown to be accounted for by the introduction of the hybrid model combining it with the extended cluster model. The hybrid model leads us to a plausible explanation of the binding mechanism of the 9Li+n+n three body system in which no pair of the constituent particles forms a bound state.
