N1 - Funding Information:
The experiment was performed at Radioactive Ion Beam Factory operated by RIKEN Nishina Center for Accelerator-Based Science and Center for Nuclear Study, University of Tokyo. The investigation became reality thanks to the outstanding collaboration between accelerator scientists and technicians as well as nuclear physicists. We deeply acknowledge the great help of the operators of RILAC and thank for the excellent performance of the accelerator. This research was partially supported by a Grant-in-Aid for Specially Promoted Research, 19002005, 2007, from the Ministry of Education, Culture, Sports, Science, and Technology of Japan.

N2 - The fusion reaction 48Ca + 248Cm → 296Lv∗ was investigated using the gas-filled recoil ion separator GARIS at RIKEN. The reaction was studied at excitation energies of 41.3 and 38.2 MeV. A total of seven decay chains were observed. Three of the chains were assigned to the decay of 292Lv and three to the decay of 293Lv. A possible observation of an α-decay branch of 284Cn populating the new spontaneously fissioning nucleus 280Ds is discussed. The assignment of one of the decay chains to the 3n evaporation channel, resulting in a spontaneous fission branch of 285Cn, or to the 2n channel, resulting in the population of the new fissioning nucleus 286Cn, is ambiguous. Measured cross sections are in agreement with previously published values.
