Groundbreaking Discovery: Scientists Identify Lightest Isotope of Astatine, Shedding Light on Atomic Nuclei Structure

Researchers at the Accelerator Laboratory of the University of Jyväskylä, Finland, have made a groundbreaking discovery in the field of nuclear physics. They have successfully created a new atomic nucleus, 190-Astatine, which is now the lightest known isotope of the rare and rapidly decaying element astatine.

The achievement of creating this novel isotope was made possible through the fusion of 84Sr beam particles with silver target atoms. The researchers used the RITU recoil separator’s detectors to identify the isotope amid the fusion products.

This remarkable scientific breakthrough was made by Master of Science graduate Henna Kokkonen as part of her thesis work. The discovery of 190-Astatine provides important insights into the structure of atomic nuclei and pushes the boundaries of our understanding of matter.

Astatine is a rare element that is known for its fast decay. It is estimated that there is no more than one tablespoon of astatine in the Earth’s crust. The creation of 190-Astatine, consisting of 85 protons and 105 neutrons, is a significant advancement in our knowledge of this elusive element.

The new isotope emits alpha particles and decays via alpha decay towards more stable isotopes. Alpha decay is a common decay mode of heavy nuclei. Understanding the properties and behavior of new nuclei like 190-Astatine is crucial for advancing our understanding of atomic nuclei and the limits of known matter.

It is worth noting that the discovery of 190-Astatine was published in the peer-reviewed journal Physical Review C, which is uncommon for a master’s thesis. Henna Kokkonen’s work and analysis of experimental data led to the identification of this new isotope. She is now continuing her studies as a Doctoral Researcher in the Accelerator Laboratory of the University of Jyväskylä, further contributing to the field of nuclear physics.

This groundbreaking research opens up new possibilities for studying atomic nuclei and expanding our knowledge of the fundamental building blocks of matter. The discovery of 190-Astatine serves as a testament to the dedication and expertise of the researchers at the Accelerator Laboratory of the University of Jyväskylä, and it paves the way for future advancements in the field of nuclear physics.

How does the creation of 190-Astatine contribute to our understanding of the fundamental building blocks of matter?

Protons and 106 neutrons, making a total of 190 particles, thereby forming the new atomic nucleus. This is a significant milestone in nuclear physics as it expands our understanding of the fundamental building blocks of matter.

Astatine, element number 85 on the periodic table, is an extremely rare element that exists only in trace amounts on Earth. It is highly radioactive and rapidly decays into other elements. Due to its scarcity and short half-life, studying astatine and its isotopes has been a formidable challenge for scientists.

The creation of 190-Astatine opens up new possibilities for further research in nuclear physics.
