抄録

A gas-jet transport system for the superheavy element chemistry was coupled to the gas-filled recoil ion separator GARIS at the RIKEN Linear Accelerator. The performance of the system was investigated using <SUP>206</SUP>Fr and <SUP>245</SUP>Fm produced in the <SUP>40</SUP>Ar-induced reactions on <SUP>169</SUP>Tm and <SUP>208</SUP>Pb targets, respectively. Alpha particles of <SUP>206</SUP>Fr and <SUP>245</SUP>Fm separated with GARIS and transported by the gas-jet were measured with a rotating wheel system for α spectrometry under low background condition. The high gas-jet efficiency of over 80% was found to be independent of the beam intensity up to 2 particle μA. These results suggest that the GARIS/gas-jet system is a promising tool for future superheavy element chemistry at RIKEN.
