Abstract

The decay properties of ²⁶⁴Hs and ²⁶⁵Hs produced in the ^207,208Pb(⁵⁸Fe,xn) (x =1;2) reactions were studied using a gas-filled recoil ion separator at the linear accelerator facility of RIKEN. A total of six decay chains were assigned to ²⁶⁴Hs. The cross sections of ²⁶⁴Hs produced in the ²⁰⁸Pb( ⁵⁸Fe,2n) and ²⁰⁷Pb(⁵⁸Fe,n) reactions were measured to be 2.8^+6.5_-2.3 and 6.9^+4.4 _-3.1 pb, respectively. The isotope ²⁶⁴Hs decayed by α-particle emission (five events) and spontaneous fission (one event). The α-particle energy of ²⁶⁴Hs was observed at 10.61 ± 0.04 and 10.80 ± 0.08 MeV.
