Japanese team get nod to name element
Print Edition
A TEAM of Japanese scientists have met the criteria for naming a new element, the synthetic highly radioactive element 113, a dozen years after they began working to create it.
Kosuke Morita, who was leading the research at the Riken Nishina Center for Accelerator-Based Science, was notified of the decision yesterday by the United States-based International Union of Pure and Applied Chemistry.
鈥淣ow that we have conclusively demonstrated the existence of element 113, we plan to look to the unchartered territory of element 119 and beyond,鈥 Morita said in a statement.
A joint working group of the IUPAC and International Union of Pure and Applied Physics also announced decisions on recognition of discoveries of elements 115, 117 and 118.
Discoveries of atomic elements often involve competition between scientists. The news is a morale booster for Riken, which has undergone a reorganization of some of its research following a scandal over stem-cell research.
鈥淭o scientists, this is of greater value than an Olympic gold medal,鈥 said Ryoji Noyori, former Riken president and Nobel laureate in chemistry.
Riken had earlier said japonium might be proposed as a name for element 113, which provisionally had been named ununtrium.
However, Morita has no specific candidates under consideration. He said he planned to spend part of next year considering a name for the element.
The IUPAC group gave collaborating teams from the Joint Institute for Nuclear Research in Dubna, Russia; Lawrence Livermore National Laboratory in California and the Oak Ridge National Laboratory in Oak Ridge, Tennessee the right to name elements 115 and 117. Separately, scientists from the Dubna laboratory and Lawrence Livermore were invited to name element 118.
Element 113 sits between copernicium and flerovium on the periodic table. A joint team of scientists in Russia and the Lawrence Livermore National Laboratory in the US also were vying for naming rights for 113 after announcing its discovery in 2004.
