Scientists Discover Heaviest Proton-Emitting Nucleus After Nearly 30 Years
Researchers at Finland’s University of Jyväskylä have identified astatine-188, the heaviest atomic nucleus yet known to undergo proton emission. This rare radioactive decay challenges established nuclear models and offers new insight into the structure and stability of exotic isotopes. The breakthrough, published in Nature Communications, marks a major step forward in understanding the limits of atomic matter.
