Element 113 Clinched?

摘要

Researchers in Russia and Japan have sparred for nearly a decade over who first observed an atom of superheavy element 113. Now, the Japanese team from the RIKEN Nishina Center for Accelerator-Based Science in Wako says a new atom of 113-its third-should cement its claim. Researchers make superheavy elements by firing nuclei at foil made of a heavy element, hoping that a projectile fuses with a target nucleus.
