Abstract

The production of 283Cn in the hot fusion reaction of 238U(48Ca,3n) was confirmed using a new gas-filled recoil ion separator GARIS-II. At the excitation energies of the compound nucleus E* = 34.5 MeV, two decay events from 283Cn were observed, resulting in the cross section of σ3n = 2.0-1.3+2.7 pb. One is the spontaneous fission with decay time τ = 14.4 s. The other is the 9.45 MeV α-decay with τ = 5.4 s, followed by the spontaneous fission of 279Ds (154 ms).
