Abstact:

The first evidence for a new spontaneous fission decay has been observed in the evaporation residues for the reaction 30Si +238U at the bombarding energy of 158 MeV. The measured half-life is 54+98−21 s and the production cross section is 180+240−120 pb. The observed spontaneous fission decay is a possible candidate for the spontaneous fission decay of 264Sg or 263Db after the β-decay of 263Sg.
