Physicists Discover Aluminium-20, a New Three-Proton-Emitting Isotope

In a study published in Physical Review Letters on July 10, physicists have reported the first observation and spectroscopy of aluminium-20, a previously unknown and unstable isotope that decays via the rare process of three-proton emission.Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic nu...

Nuclear Mass Measurement Reveals New Proton Magic Number

Researchers have precisely measured for the first time the mass of an extremely short-lived and neutron-deficient nucleus, silicon-22, revealing that the proton number 14 in silicon-22 is a new magic number.“Magic numbers” in nuclear physics identify specific numbers of protons or neutrons that lead to especially stable nuclei. Recognizing these numbers helps scientists better understand the structu...

Studies Offer New Insights into Production and Structure of Heavy Hollow Atoms

Researchers have recently confirmed that the fully stripped heavy ion-atom collision is an effective way to produce heavy hollow atoms in high yield. And they developed a high-resolution planar crystal spectrometer for measuring the fine structure of inner-shell multi-ionization ion X-rays.Hollow atoms are special atoms with multiple missing electrons in their inner shells, while their outer shells are still fully or partially filled with electrons. Studying the production mechanisms...
