Synthesis and chemistry of new elements at RIKEN



Since the official approval of four new heavy elements with atomic number Z = 113, 115, 117, and 118 by IUPAC in 2016, the 7th period of the periodic table of the elements has been complete. Element 113 was synthesized in the fusion reaction of 70Zn (Z = 30) on 209Bi (Z = 83) using the Gas-filled Recoil Ion Separator (GARIS) at the RIKEN linear accelerator facility. The name “nihonium”and symbol “Nh” were given for the new element, the first discovered in Asian countries. An attempt to create element 119 is under way through the 248Cm (Z = 96) + 51V (Z = 23) reaction. To study chemical properties of the new elements, we have been developing a novel chemistry setup using GARIS.
