[en] The ⁶Li nucleus is considered as composed of an alpha particle, a proton and a neutron. With this construction the ⁶Li nucleus is studied as a three-body problem. The Faddeev equations are given, taking separable potentials for the interaction between the alpha, the proton and the neutron particles in pairs. The nucleon-nucleon potential is taken as a central term of the Yamaguchi type and also including a tensor force. To investigate the short-range correlations in this three-body system, the nucleon-nucleon potential is taken to include a repulsive soft-core part in addiation to the attractive part ocnsidered. The nucleon-alpha potential is taken as central and spin-orbit terms which fit the corresponding experimental nucleon-alpha phase shifts. The effect of Coulomb forces between the proton and the alpha particle is taken into account. Solving the coupled Faddeev equations numerically, the binding energies for the ground and excited states of ⁶Li are calculated. Inclusion of repulsive-core effects is found to change the results by 19%
