An isotope of element 104, rutherfordium (261Rf), produced in the 248Cm(18O, 5n)261Rf reaction was successfully extracted to a chemistry laboratory using a gas-jet transport system coupled to the RIKEN gas-filled recoil ion separator GARIS. The present system is a promising interface to explore new frontiers in superheavy element chemistry.

The convincing candidate event of the isotope of the 113th element, 278113, and its daughter nuclei, 274111 and 270Mt, were observed, for the first time, in the 209Bi+70Zn reaction at a beam energy of 349.0 MeV with a total dose of 1.7×1019. Alpha decay energies and decay times of the candidates, 278113, 274111, and 270Mt, were (11.68±0.04 MeV, 0.344 ms), (11.15±0.07 MeV, 9.26 ms), and (10.03±0.07 MeV, 7.16 ms), respectively. The production cross section of the isotope was deduced to be 55+150−45 fb (10−39 cm2).
