As hindrance sets in for the fusion of heavier systems, the effect of large neutron excess in the colliding nuclei on their probability to fuse is still an open question. The detection of evaporation residues (ERs), however, provides indisputable evidence for the fusion (complete and incomplete) in the reaction. We therefore devised a system with which we could measure ERs using low intensity neutron-rich radioactive ion beams with an efficiency close to 100%. We report on measurements of the production of ERs in collisions of 132,134Sn, 134Te and 134Sb ion beams with medium mass, neutron-rich targets. The data taken with 132,134Sn bombarding a 64Ni target are compared to available data (ERs and fusion) taken with stable Sn isotopes. Preliminary data on the fusion of 132Sn with 96Zr target are also presented.
