By using the d--..cap alpha.. 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/sup +/,0) ground state, (3/sup +/,0) 1st excited state, (2/sup +/,0) 3rd excited state, and (1/sup +/,0) 5th excited state of /sup 6/Li are studied by phase-shift analysis and generalized eigenvalue analysis with the single-channel resonating-group-method (RGM). The results show that, from the phase-shift and eigenvalue analyses, the ground state of /sup 6/Li is mainly an l = 0 d--..cap alpha.. cluster-structure bound state, and the 1st, 3rd, and 5th excited states of /sup 6/Li are mainly (l,J) = (2,3), (2,2), and (2,1) unbound cluster-structure states, respectively.
