摘要：
The hyperspherical harmonics expansion method is applied to a three-body model of two-neutron halo nuclei. Convergence of the expansion has been ensured. A short-range repulsive part is incorporated in the interaction between the core and the extra-core neutron, to simulate the Pauli principle. Two neutron separation energy, rms radii, correlation factor and halo neutron density distributions have been calculated for Li-11. It is found that the convergence of the two-neutron separation energy is relatively slow, while other quantities reach convergence quickly.
