Abstract
Effects of the coupling to +d nonresonant continuum states on polarized scattering at ≃20–100 MeV are investigated in the framework of the continuum-discretized coupled-channels (CDCC) method which takes into account the resonant and nonresonant α-d breakup states of . A convergence of the calculated analyzing powers of 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 α-d S-wave (l=0), P-wave (l=1), and D-wave (l=2) states up to the α-d relative momentum of k=1.2 . 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.
