For a wide range of incident energy (E/sub lab/ = 40--170 MeV) and target mass number (A = 12--208), projectile breakup effects in elastic scattering of /sup 6/Li have been investigated in the microscopic coupled-channel framework; coupling with /sup 6/Li..--> cap alpha..+d breakup process is taken into account by the method of coupled discretized continuum channels. /sup 6/Li-target interactions are provided by folding of the M3Y effective nucleon-nucleon potential with nucleon densities of colliding nuclei. The calculation reproduces well experimental data of elastic scattering for all the targets and incident energies investigated, without any renormalization of the folding real potential. The breakup effect is found to depend little on the energy and target, which is shown by calculating dynamical polarization potentials induced by the breakup process. The dynamical polarization potential has a repulsive real part with strength of about 40% of the folding potential, the imaginary part being negligible, which explains well the empirical reduction factor of the single-channel double-folding model. The origin of repulsive nature of the breakup effect is discussed.
