| Fusion-evaporation in the 124Sn+136Xe system is studied using a high intensity xenon beam
provided by the Ganil accelerator and the LISE3 wien _lter for the selection of the products. Due to the
mass symmetry of the entrance system, the rejection of the beam by the spectrometer was of the order of
5_108. We have thus performed a detailed statistical analysis to estimate random events and to infer the
fusion-evaporation cross sections. No signicant decay events were detected and upper limit cross sections of 172 pb, 87 pb and 235 pb were deduced for the synthesis of 257Rf, 258Rf and 259Rf, respectively.
