Investigation of the role of the breakup process on the fusion and scattering of weakly bound projectile induced reactions

The role of the breakup process of the weakly bounded light projectiles Li- 6,Li-7 and Be-9, on the near barrier fusion reaction and elastic scattering , is investigated by two different approaches. The measurements of the elas tic scattering for the Li-6,Li-7 + Ba-138 and Be-9 + Zn-64 systems were use d to study the threshold anomaly, and the fusion cross sections for the Be- 9 + Zn-64 system were compared with the ones from other similar systems (th e O-16 + Zn-64 and N-14 + Co-59). There are signatures of fusion suppressio n only for the Li-6 + Ba-138 system.
