A detector (RFD) has been developed that measures evaporation residues in coincidence with gamma-rays in a Ge-array. Evaporation residues are distinguished by time of flight from any other reaction products with different velocity, like from fission and reactions with light target impurities, and the background from these processes is eliminated. Also the energy of the gamma-rays can be Doppler corrected event by event with the measured velocity vector of the emitting nucleus improving the resolution. Recent results of experiments with OSIRIS at VICKSI on 189Pb and nuclei around doubly magic 56Ni, that show the performance of the detector, are presented and the perspectives of the RFD application with EUROBALL are discussed.
