Fusion cross sections were measured for A045300100009 the 6,7-Li+27-Al, 64-Zn systems, at energies above the A045300100010 the coulomb barrier, in order to study the influence ofA045300100011 the breakup of stable weakly bound nuclei on the fusionA045300100012 process. The analysis was completed by the inclusion A045300100013 of the data of fusion induced by 9-Be and the strongly A045300100014 bound 16-O and 11-B projectiles on the same targets. A045300100015 The fusion excitation functions have similar behavior A045300100016 for all projectiles incident on both targets and they A045300100017 show no indication of fusion hindrance. A045300100018 - By authors:.The masses of residual nuclei originatingA045300100019 from the complete fusion and those from the incomplete A045300100020 fusion are mostly the same, and we were not able to A045300100021 separate complete fusion from incomplete fusion. A045300100022 Therefore, the measured fusion cross sections A045300100023 correspond to the sum of these two proccesses.
