Element 114 Confirmed

Eight-day-long atom-smashing experiment reproduces 10-year-old result
Department: Science & Technology
Keywords: element 114, superheavy elements, transactinide

Ten years after scientists in Dubna, Russia, first reported synthesizing nuclei of element 114 in a high-energy accelerator, researchers at Lawrence Berkeley National Laboratory have independently confirmed those results, according to a study published in Physical Review Letters (2009, 103, 132502). Reproducing experimental results is the bedrock of the scientific method. Yet the extremely low probability of making superheavy nuclei, which in the case of element 114 was done by firing 48Ca ions into a . . .
