Abstract：
By using the d-α cluster-structure wave function and the nucleon-nucleon (N-N) force containing a soft-repulsive core central potential and a spin-orbit noncentral potential, the (1⁺, 0) ground state, (3⁺, 0) 1st excited state, (2⁺, 0) 3rd excited state, and (1⁺, 0) 5th excited state of ⁶Li are studied by phase-shift analysis and generalized eigenvalue analysis with single-channel resonating group-method (RGM). The results show that, from the phase-shift and eigenvalue analyses, the ground state of ⁶Li is mainly an l=0 d-α cluster-structure bound state, and the 1st, 3rd, and 5th excited states of ⁶Li are mainly (1,J)=(2,3), (2,2), and (2,1) cluster-structure unbound states, respectively.
