Researchers at the University of Jyväskylä have measured the decay of the heaviest nucleus emitting protons for the first time in nearly 30 years, identifying a new isotope of astatine (188At) and expanding understanding of nuclear structure and interactions.
Physicists have discovered a new atomic nucleus called nitrogen-9, which exists for only one billionth of a nanosecond. Despite its extremely short lifespan, many scientists consider it a nucleus and believe that studying such fleeting nuclei could expand our understanding of nuclear theory and quantum mechanics.
Researchers at the University of Jyväskylä in Finland have discovered the lightest isotope of the rare and rapidly decaying element, astatine. The new atomic nucleus, 190-Astatine, was created through the fusion of 84Sr beam particles with silver target atoms. The isotope was identified using the RITU recoil separator’s detectors. The discovery provides important insights into atomic nuclei structure and the boundaries of known matter.
A new atomic nucleus, 190-Astatine, consisting of 85 protons and 105 neutrons, has been discovered by a researcher at the University of Jyväskylä in Finland. The isotope was produced in the fusion of 84Sr beam particles and silver target atoms and detected using a RITU recoil separator. The new nuclei decay via alpha decay towards more stable isotopes. The discovery is important for understanding the structure of atomic nuclei and the limits of known matter.
