Researcher discovers new isotope of astatine

An experiment performed in the Accelerator Laboratory of University
of Jyvaskyla, Finland, has succeeded in producing a previously
unknown atomic nucleus, 190-Astatine, consisting of 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. 190-Astatine, the new isotope, was produced
in the fusion of ^84Sr beam particles and silver target atoms. The
isotope was detected among the products by using the detectors of a
RITU recoil separator.
New nucleus emits alpha particles
The new nuclei decay via alpha decay towards more stable isotopes.
Alpha decay is a common decay mode of heavy nuclei.
"The studies of new nuclei are important for understanding the
structure of atomic nuclei and the limits of known matter," says
Doctoral Researcher Henna Kokkonen from the Department of Physics,
University of Jyvaskyla.
The new discovery was made by Kokkonen, who recently graduated with a
Master of Science degree. The study was a part of her master's
thesis, and the research is published in the journal Physical Review
C.
"In my thesis, I analyzed experimental data among which the new
isotope was found. During my thesis process and summer internships I
got to know the Nuclear Spectroscopy group's work. Now I am very
happy to work in the group towards my Ph.D. degree," says Kokkonen.
