Research Abstract

A novel elemental analysis system for superheavy elements (SHEs, atomic numbers Z≧104) has been developed by directly coupling a cryogenic gas-chromatograph apparatus to the gas-filled recoil ion separator (GARIS) at the RIKEN linear accelerator facility. The productions and decay properties of ^<261>Rf (element 104, rutherfordium) and ^<265>Sg (element 106, seaborgium) were investigated for the future SHE chemistry using the GARIS gas-jet system and a rotating wheel system for α-spectrometry.
