抄録

The fusion reaction 48 Ca + 248 Cm → 296 Lv∗ 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 292 Lv and three to the decay of 293 Lv. A possible observation of an α-decay branch of 284 Cn populating the new spontaneously fissioning nucleus 280 Ds is discussed. The assignment of one of the decay chains to the 3n evaporation channel, resulting in a spontaneous fission branch of 285 Cn, or to the 2n channel, resulting in the population of the new fissioning nucleus 286 Cn, is ambiguous. Measured cross sections are in agreement with previously published values.
