Phys. Rev. C 68, 044605 (2003) [5 pages]Near barrier fusion excitation function of 6Li+208PbReceived 7 September 2002; revised 15 May 2003; published 10 October 2003 The fusion cross sections of 6Li+208Pb system at energies near the barrier have been measured by means of the evaporation residue method and have been calculated in terms of the coupled-channels model, taking into account single and double phonon octupole excitations of 208Pb and the 3+ rotational state of 6Li. By comparing the experimental results with the theoretical calculations and with the fusion cross section of 16O+208Pb, in which no breakup happens, we conclude that the fusion cross sections of 6Li+208Pb are suppressed at above-barrier energies due to the effects of 6Li breakup, but below the barrier, the effects of breakup are not clear. © 2003 The American Physical Society URL:
