Scientists have discovered the heaviest atomic nucleus ever observed, astatine-188, that decays by emitting a proton.
This rare discovery was made at the Accelerator Laboratory of the University of Jyväskylä in Finland, showcasing the extreme instability of the nucleus.
Published in Nature Communications, the research involved creating astatine-188 through fusion-evaporation and studying it with advanced technology like the RITU recoil separator.
The unique properties of astatine-188, including its elongated shape and novel interactions, contribute to advancing our understanding of nuclear physics and the limits of matter.
