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.
