SHE research at RIKEN/GARIS

In this contribution, heavy-element research at RIKEN, Japan is reviewed. Nuclei of the heaviest elements were produced by the reactions 208Pb(64Ni, n)271Ds, 209Bi(64Ni, n)272Rg, 208Pb(70Zn, n)277Cn, and 209Bi(70Zn, n)278113. Alpha decays of those products and their consecutive alpha/spontaneous fission decays were studied using a gas-filled type recoil separator. New nuclei, 278113, 274Rg, and 270Mt, were observed in the 209Bi + 70Zn reaction.
