Resonant breakup processes in the 6,7Li+144Sm systems is studied through the results obtained in exclusive measurements performed at energies around the Coulomb barrier and a kinematical description of these phenomena is introduced. For the 7Li projectile, dominance oftransfer breakup through the 6Li first excited state is observed. In the 6Li projectile case, elastic breakup through the same projectile-like excited state clearly dominates the experimental yield. Relative and absolute cross sections for both systems are calculated. A clear asymmetry is observed in the intrinsic angular distributions, in good agreement with results reported for other known systems.
