COUPLING EFFECTS OF RESONANT AND DISCRETIZED NONRESONANT CONTINUUM STATES IN HE-4-6 SCATTERING AT 10 MEV(LI)A/

Alpha- particle scattering from the resonant (3(1)(+)) and non-resonan t continuum states of Li-6 is studied at incident energy 10 MeV/A. The alpha + d breakup continuum part within the excitation energy E(ex) = 1.475-2.475 MeV is discretized in two energy bins. Unlike the results at higher incident energies, here the coupled-channel calculations sh ow significant breakup continuum coupling effects on the elastic and i nelastic scattering. It is shown that even when the continuum-continuu m coupling effects are strong, the experimental data of the ground sta te and the resonant as well as discretized non-resonant continuum stat es impose stringent constraint on the coupling strengths of the non-re sonant continuum states.
