Large Hadron Collider experiments reveal neon nucleus may be bowling-pin shaped

A recent experimental result from the Large Hadron Collider at CERN suggests that the internal structure of the neon-20 nucleus may not be approximately spherical as commonly depicted in traditional textbooks, but rather closer to a "bowling pin" shape. This finding provides new experimental clues for studying deformation of light atomic nuclei and collective behavior in high-energy nuclear collisions. Atomic nuclei are composed of protons and neutrons, determining the elemental identity of atoms and carrying most of their mass. Although nuclei are often simplistically depicted as spherical, nuclear physics research has shown that some nuclei exhibit pronounced non-spherical deformation, such as the pear-shaped nuclei mentioned in previous studies. Accurately understanding these shapes helps physicists...

US FRIB Experiment Reveals Magnetic Origin of Anomalous Low-Energy Gamma-Ray Enhancement

According to an August 21 announcement from Lawrence Livermore National Laboratory, a new study led by the U.S. Facility for Rare Isotope Beams (FRIB) with participation from researchers at Lawrence Livermore National Laboratory and other institutions has provided a new experimental explanation for the long-standing low-energy enhancement phenomenon in nuclear physics. The findings were published in the journal Nature. An experiment at the Facility for Rare Isotope Beams (FRIB) has yielded new results, answering a fundamental question about nuclear structure. (Image: FRIB) Gamma rays are a form of electromagnetic radiation. When an excited nucleus loses energy during radioactive decay and transitions to a lower, more stable energy level, it emits gamma rays. Over the past few decades, scientists have discovered that certain nuclei emit anomalously large numbers of low-energy gamma rays, but this phenomenon does not occur in all nuclei, and its occurrence conditions have been difficult to predict reliably in theory.

U.S. SYNOPTICS Produces Large-Size Yb:YLF Crystal for Inertial Confinement Fusion Laser Systems

On August 19, SYNOPTICS, a subsidiary of Northrop Grumman, announced that it had successfully grown and harvested a large-size ytterbium-doped yttrium lithium fluoride crystal, namely a Yb:YLF crystal ingot. The crystal measures approximately 127 millimeters at its widest point, with a diameter three times the industry standard. SYNOPTICS stated that as laser engineering continues to expand toward higher efficiency and higher power, the demand for gain media with larger apertures and larger dimensions continues to grow. The Yb:YLF crystal produced this time is approximately 20% larger than the largest crystal the company had previously grown, and approximately 50% larger than the company's conventional product size. Kevin Stevens, General Manager of SYNOPTICS, stated that yttrium lithium fluoride is a commonly used host material for laser-active rare-earth ions, and scaling up the growth of YLF crystals will help laser engineers continue to raise the upper limit of achievable laser output power. He said that such materials are of significant importance for applications including directed energy, inertial confinement fusion, and industrial laser systems. Stevens also stated that Yb:YLF crystals can be used in applications requiring reduced thermal lensing effects and enhanced pulsed energy storage capability, while also leveraging their natural birefringent host to achieve polarization characteristics. According to information recently released by SYNOPTICS, some of the crystals will be used in the high-energy laser system at the German Electron Synchrotron Research Center (DESY) to support its inertial confinement fusion energy research. The company is currently studying the feasibility of further scaling up the size of Yb:YLF crystals, and plans to extend the relevant processes to other rare-earth-ion-doped YLF crystals, including holmium, thulium, and neodymium doping systems.

South Korea Amends Nuclear Safety Act to Clarify Safety Responsibilities of Nuclear Facility Operators

The National Assembly of South Korea passed a partial amendment to the Nuclear Safety Act at its 438th special session on August 20, marking the first time that nuclear-related business operators' primary responsibility for nuclear facility safety has been explicitly established at the legal level. This move signifies that South Korea's nuclear safety management system will further transition from a licensing and regulation-centered approach to a responsibility system aligned with the safety principles of the International Atomic Energy Agency (IAEA). The amendment was proposed by South Korean lawmaker Oh Se-hee. Prior to the revision, South Korea's Nuclear Safety Act primarily established safety standards and regulatory procedures around reactor construction and operating licenses, nuclear material use, and radioactive waste management facility operations, but lacked...
