摘要：

By using the hybrid-TV model of the He-4+n+n three-body system, the binding energy and excited states of He-6 are investigated. The binding energy 0.784 MeV is obtained for more realistic He-4-n interaction. It is discussed that the n-n correlations, which are fully taken into account in the ECM bases, are very important to reproduce the binding energy of He-6. The excited resonance states of the He-6 system are also calculated by applying the complex scaling method. The first excited 2(+) state obtained as a three-body resonance state is in good agreement with experiments. However, the excited 1(-) resonance states corresponding to the soft dipole excitation are not obtained at the low energy region.
