New Superheavy Isotope ²⁵⁷Sg Sheds Light on Nuclear Stability and K-Isomers Unveiling  ²⁵⁷Sg: A New Window into Nuclear Stability A recent publication in Physical Review Letters details the discovery of a new superheavy isotope,  ²⁵⁷Sg (seaborgium), by researchers at GSI Helmholtzzentrum, offering fresh perspectives on the nuclear stability and fission behaviour of the heaviest elements. Superheavy elements occupy a finely tuned equilibrium between the nuclear force binding protons and neutrons and the electromagnetic force driving protons apart. Were it not for quantum shell effects — akin to electron shells in atoms —these colossal nuclei would disintegrate in under a trillionth of a second. Publisher website interviewed Dr. Pavol Mosat and Dr. J. Khuyagbaatar, co-authors of the study from GSI Helmholtzzentrum  für  Schwerionenforschung in Germany, regarding their research. The findings highlight gaps in our understanding of extreme atomic nuclei, hinting that the...

First Ever Nuclear Reaction in Neutron Star Remnants Measured Using Nanomaterials A Breakthrough in Astrophysics and Nuclear physics Physicists have successfully observed a nuclear reaction that takes place during neutron star collisions, offering experimental data for a process that was once purely theoretical. this research, conducted by the University of Surrey, sheds light on the creation of the universe's heaviest elements and may lead to breakthroughs in nuclear reactor technology. Historic First Measurement of a Weak r-Process Reaction The ⁹⁴Sr(α,n)⁹⁷Zr  Nuclear Reaction In collaboration with the University of York, University of Seville, and TRIUMF — Canada's national particle accelerator center — researchers have achieved a historic milestone: the first direct measurement of a week r-process reaction cross-section using a radioactive ion beam. This study focused on the  ⁹⁴Sr(α,n)⁹⁷Zr reaction, where strontium-94 absorbs an alpha particle, emits a neutron, and tra...

Nuclear Physics Breakthrough: New Calculation Links Disparate Pion Reactions Introduction to the Groundbreaking Lattice QCD Calculation A physicist at the early stage of their career has made a mathematical breakthrough linking timelike and spacelike from factors, offering new pathways to understanding force. This innovative lattice QCD calculation establishes a connection between two  previously unrelated  reactions involving the pion, the lightest particle influenced by the strong interaction. Felipe Ortega-Gama's Early research and Mentorship at Jefferson Lab Undergraduate Research and Mentorship at  Tecnológico  de Monterrey During his undergraduate studies at  Tecnológico de Monterrey, Mexico, Felipe Ortega-Gama participated in the U.S. Department of Energy's Science Undergraduate Laboratory Internships program at the Thomas Jefferson National Accelerator Facility. Under the mentorship of  Raúl Briceño , a staff scientist at the lab's Center for Theore...

New Study Unveils Overlooked Nuclear Force That Stabilizes Matter Kyushu University Researchers Discover  Three-Nucleon Force's Role in Nuclear Stability Researchers at Kyushu University, have uncovered how the three-nucleon force within an atom's nucleus influences nuclear stability. Their study in Physics Letter B   sheds light on why certain nuclei are more stable and offers insights into astrophysical processes, such as the formation of heavy elements in stars. The Nucleus: The Heart of Atomic Matter Atoms, the fundamental constituents of matter, serve as the building blocks of the universe. The majority of an atom's mass is concentrated in its minuscule nucleus, which consists of protons and neutrons, collectively termed nucleons. For over a century, a key focus in nuclear physics has been understanding the interactions between these nucleons that ensure nuclear stability and maintain a low-energy state. The Two-Nucleon Force: The Strongest Nuclear Interaction The str...

Unveiling the Mystery: New Insights into Mass Distribution in Hadrons Introduction to Mass in Subatomic Particles Examining the Energy and Momentum of Quarks Scientists determine the mass of subatomic particles made of quarks by examining their energy and momentum in four-dimensional s pacetime. The Trace Anomaly and Its Role The trace anomaly, an essential metric, ties to the energy/momentum scale de pendence observed in high-energy  physics. The Im portance of the Trace Anomaly in Quark Binding How the Trace Anomaly Affects Quark Binding Scientists  posit that the trace anomaly  plays an essential role in maintaining the binding of quarks within subatomic  particles. Study Insights: Calculating the Trace Anomaly A study   published in Physical Review D  presented calculations of the trace anomaly for nucleons, including  protons and neutrons, as well as for  pions, com posed of one quark and one antiquark.

Exploring ¹⁰⁰Sn: Strong Evidence for its Rare Doubly Magic Properties Introduction New experiments at CERN have provided valuable insights into the nuclear characteristics of atomic nuclei, which make up the majority of atomic mass. A major focus has been on understanding Tin-100 ( ¹⁰⁰Sn ), a rare isotope with an equal number of protons and neutrons — 50 each. Magic Numbers in Nuclear Physics In nuclear physics, these particular counts of protons and neutrons are termed ' magic numbers .' This designation indicates that the isotope possesses fully filled proton and neutron shells, resulting in an exceptionally stable nuclear configuration. Breakthrough Findings on Tin-100 A team of researchers from MIT, the university of Manchester, CERN, KU Leuven, and other institutions recently presented compelling evidence indicating that Tin-100 ( ¹⁰⁰Sn ) exhibits a doubly magic nucleus. Published in Nature Physics , their findings pave the way for groundbreaking research to test and refi...

First Coherent Representation of Atomic Nucleus: Uniting Quarks and Gluons in Nuclear Physics Introduction to the Atomic Nucleus The atomic nucleus consists of protons and neutrons, whose existence arises from the interaction of quarks bound together by gluons. One might assume, then, that recreating all the  pro perties of atomic nuclei observed in nuclear ex periments using only quarks and gluons would be straightforward. Yet, it is only recently that  physicists, including those at the Institute of Nuclear Physics of the Polish Academy of Sciences in Krakow, have achieved this. Historical Context Discovery of Protons and Neutrons Nearly a century has  passed since the discovery of the key com ponents of atomic nuclei: P rotons and Neutrons. At first, these  particles were believed to be indivisible. However, in the 1960s, it was  pro posed that at sufficiently high energies,  protons and neutrons would ex pose their internal structure--quarks bound toge...
