EFFECTS OF NONRESONANT BREAKUP STATES IN POLARIZED LI-6 SCATTERING

Effects of the coupling to Li-6 --> alpha + d nonresonant continuum states on polarized Li-6 scattering at E(lab) congruent-to 20-100 MeV are investigated in the framework of the continuum-discretized coupled-channels (CDCC) method which takes into account the resonant and nonresonant alpha-d breakup states of Li-6. A convergence of the calculated analyzing powers of Li-6 elastic scattering against the size and the discretization of the breakup continuum is examined. The resulting model space of the breakup states consists of the alpha-d S-wave (l = 0), P-wave (l = 1), and D-wave (l = 2) states up to the alpha-d relative momentum of k = 1.2 fm-1. The results of the CDCC calculation show that the effects of the nonresonant breakup states are quite as significant on the analyzing powers as those of the resonant breakup states.
