Particle Accelerator Reveals A New Type of Atomic Nucleus

Finland's University of Jyväskylä has an announcement: an experiment performed in its accelerator lab "has succeeded in producing a previously unknown atomic nucleus."
Dubbed "190-Astatine," it's made from 85 protons and 105 neutrons..
The nucleus is the lightest isotope of astatine discovered to date. Astatine is a fast-decaying, and therefore rare element. It has been estimated that in the Earth's crust, there is no more than one tablespoon of astatine...
The new isotope was produced
