Abstract

Measurements of complete and incomplete fusion cross sections for Li6+Sm154 have been performed at energies above the Coulomb barrier by the online γ-ray method, to investigate the effect of breakup and inelastic couplings on the complete fusion (CF) of this weakly bound system. We show that inelastic excitation couplings have non-negligible effects, when compared with the breakup effect, for deformed nuclei at energies very close to the Coulomb barrier. The average CF suppression corresponding to dynamic breakup effects was found to be around 35%. The total fusion cross section is not affected by the breakup coupling. A comparison between the Li6-induced CF suppression for three different samarium isotopes shows that the breakup effect is larger for the more spherical isotope.
