Research Abstract

A novel elemental analysis system for superheavy elements (SHEs, atomic numbers Z > 103) in gas phase was developed by directly coupling a gas chromatograph apparatus to the gas-filled recoil ion separator (GARIS) at the RIKEN linear accelerator facility. The production and decay properties of isotopes of element 105, 262Db, and element 106, 265Sg, were investigated for the future SHE chemistry using the GARIS gas-jet system and a rotating wheel system for alpha/SF-spectrometry (SF: Spontaneous Fission). A carbonyl complex of Sg(CO)6, was synthesized with the GARIS gas-jet system and its volatility was investigated with the thermochromatography detector array COMPACT developed by the SHE chemistry group of GSI.
