Description
CDCC calculations of total fusion cross sections for reactions of the weakly bound $^{6}$Li with targets $^{28}$Si, $^{59}$Co, $^{96}$Zr, $^{144}$Sm and $^{209}$Bi at energies around the Coulomb barrier are presented. In the cluster structure frame of $^{6}$Li$\rightarrow \alpha +d$, short-range absorption potentials are considered for the interactions between the $\alpha$ and -$d$ fragments with the targets. The effect of resonance states ($l=2, J^{\pi}=3^{+},2^{+},1^{+}$) and non-resonance states of $^{6}$Li on fusion is studied by i) omitting resonance states from the full discretized breakup space and ii) by considering only the resonance discretized space. A systematic analysis of the effect on fusion from resonance breakup couplings is carried out from light to heavy target masses.
