Japanese research institute earns right to name element 113

A team of Japanese scientists have met the criteria for naming a new element, the synthetic highly radioactive element 113, more than a dozen years after they began working to create it.

Kosuke Morita, who was leading researcher at the government-affiliated Riken Nishina Center for Accelerator-Based Science, was notified of the decision on Thursday by the U.S.-based International Union of Pure and Applied Chemistry.

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.

The 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 provisionally had been named ununtrium, and Morita said in a statement issued by Riken that he planned to spend part of next year considering a formal name for the element.

“Now that we have conclusively demonstrated the existence of element 113, we plan to look to the uncharted territory of element 119 and beyond,” he said.

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 U.S. also were vying for naming rights for 113.

Morita and his group used Riken’s linear accelerator and ion separator to search for new synthetic superheavy elements, beginning in the late 1980s. In 2003, his team began working to create element 113 by bombarding a thin layer of bismuth with zinc ions traveling at about 10 percent the speed of light, Riken said.

Isotopes of element 113 have a very short half-life, lasting for less than a thousandth of a second, making its discovery very difficult. After twice succeeding to create it, the group tried for seven years before a third success, in August 2012.

    Nice!

    Well done. Now what shall it be? Gundamium? Pokemonium? Yokaiwatchium? Evangellium? Babymetalium? Suntorium? or my personal favorite: Keroronium. :-)
