First experimental results of a chemical investigation of element 113 independently confirm the synthesis of the new elements 115 and 113 in the nuclear fusion reaction of 48 Ca + 243 Am and indicate a chemical behaviour resembling a species with a high volatility, a weak interaction with inert surfaces and an enhanced reactivity towards gold surfaces.
The recent discovery of the elements 115 and 113 in the reaction 48 Ca + 243 Am was confirmed by an independent radiochemical experiment based on the identification of the long-lived decay product dubnium.
