摘要
The He-6 nucleus is considered as the cluster alpha + n + n system. The excitation energies of the low-lying levels are calculated using the configuration-space Faddeev equations. The analytical continuation method in a coupling constant is applied for calculation of resonance parameters. The alpha n interaction is constructed to reproduce the results of R-matrix analysis for alpha n-scattering data. A realistic AV14 potential describes the nn interaction. Additional three-body potential adjusted by the ground state energy of He-6 is used. The energies of the low-lying resonances of He-6 (0 (1) (+) , 0 (2) (+) , 2 (1) (+) ) are reasonably reproduced by the calculations.
