Data for the elastic scattering of 27.8 MeV polarized 6 Li from 4 He and new data for the 6 Li→␣ϩd sequential breakup have been analyzed using the coupled-channels ͑CC͒ method with potentials derived via the cluster-folding ͑CF͒ procedure. The three low-lying Tϭ0 resonant excited states of 6 Li as well as nonresonant continuum states were taken into account in the calculations by means of the continuum-discretized coupledchannels ͑CDCC͒ method. No adjustable parameters were used. The analysis shows a dominant role of the projectile breakup into ␣ϩd in the 6 Liϩ 4 He elastic scattering. The deuteron transfer process is found to be of less importance. The calculations reproduce the values of the differential cross section for the sequential breakup channels at forward scattering angles. Predictions for the direct breakup near the 6 Li→␣ϩd breakup threshold are made. ͓S0556-2813͑97͒00210-0͔
