摘要：

We have performed continuum discretized coupled channel (CDCC) calculations for collisions of Li-7 projectiles on Co-59, Sm-144, and Pb-208 targets at near-barrier energies, to assess the importance of the Coulomb and the nuclear couplings in the breakup of Li-7, as well as the Coulomb-nuclear interference. We have also investigated scaling laws, expressing the dependence of the cross sections on the charge and the mass of the target. This work is complementary to that previously reported by us on the breakup of Li-6. Here we explore the similarities and differences between the results for the two lithium isotopes. The relevance of the Coulomb dipole and quadrupole strengths at low energy for the two-cluster projectile is investigated in detail.
