Near-barrier fusion ofLi11with heavy spherical and deformed targets

The cross sections for the fusion of ${}_{}{}^{11}{}_{}{}^{}\mathrm{Li}$ with ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ and ${}_{}{}^{238}{}_{}{}^{}\mathrm{U}$ are calculated at near-barrier energies. The coupling of the entrance channel to the soft giant dipole resonance in ${}_{}{}^{11}{}_{}{}^{}\mathrm{Li}$ is taken into account together with the coupling to the breakup channel ${}_{}{}^9{}_{}{}^{}\mathrm{Li}$+2n. The deformation of ${}_{}{}^{238}{}_{}{}^{}\mathrm{U}$ is also considered. The cross section is found to exhibit important structure around the barrier.
