Elastic scattering of the weakly bound Li6 on Al27 was measured at near-barrier energies. The data analysis was performed using a Woods-Saxon shape optical potential and also using the double-folding São Paulo potential. The results show the presence of the breakup threshold anomaly (BTA), an anomal...

Sumario:Elastic scattering of the weakly bound Li6 on Al27 was measured at near-barrier energies. The data analysis was performed using a Woods-Saxon shape optical potential and also using the double-folding São Paulo potential. The results show the presence of the breakup threshold anomaly (BTA), an anomalous behavior when compared with the scattering of tightly bound nuclei. This behavior is attributed to a repulsive polarization potential produced by the coupling to the continuum breakup states. © 2007 The American Physical Society.
