Probing the fusion of neutron-rich nuclei with re-accelerated radioactive beams

We report the first measurement of the fusion excitation functions for K + Si at nearbarrier energies. Evaporation residues resulting from the fusion process were identified by direct measurement of their energy and time-of-flight with high geometric efficiency. At the lowest incident energy, the cross-section measured for the neutron-rich K induced reaction is ∼6 times larger than that of the β-stable system. The experimental data are compared with both a dynamical deformation model and coupled channels calculations (CCFULL).
