英文摘要	A gas-filled recoil separator GARIS for heavy element research was installed at an experimental hall of the RIKEN linear Accelerator (RILAC) facility. One of the interesting applications of the separator is the discovery of nuclei of superheavy elements whose atomic number are grater then 110. We performed experiments to study productions and decays of heavy nuclei, (271)Ds and (272)111, which were produced with Pb-208 + Ni-64 --> (271)Ds + n and Bi-209 + Ni-64 --> (272)111 + it reactions. Fourteen atoms of (271)Ds and the same number of (272)111 were detected and identified. Existence of an isomeric state in (271)Ds was confirmed. In the decay chains of (272)111, spontaneous fission decays were observed in decay of (264)Bh and (260)Db.
