  • Scientists calculate predictions for meson measurements
    Calculations of charge distribution in mesons provide benchmark for experimental measurements and validate widely used 'factorization' method for imaging the building blocks of matter.
  • Imaging nuclear shapes by smashing them to smithereens
    Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC) to reveal subtle details about the shapes of atomic nuclei. The method is complementary to lower energy techniques for determining nuclear structure. It will add depth to scientists' understanding of the nuclei that make up the bulk of visible matter.
  • Successful experiment paves the way for new element
    Scientists have found an alternative way to produce atoms of the superheavy element livermorium. The new method opens up the possibility of creating another element that could be the heaviest in the world so far: number 120.
  • Molecule 'handedness' determines the strength of a coupling between nuclear spins
    Chirality -- a geometric property that allows molecules to exist in two distinct forms that are chemically identical but are 3D mirror images of each other, like a right and left hand -- has a powerful effect on nuclear spin state but was thought to have no effect on coupling between spins. A study found chirality, or handedness, does in fact determine the strength of a couplin...
  • New AI models of plasma heating lead to important corrections in computer code used for fusion research
    New artificial intelligence models for plasma heating can do more than was previously thought possible, not only increasing the prediction speed 10 million times while preserving accuracy but also correctly predicting plasma heating in cases where the original numerical code failed.
  • Stopping off-the-wall behavior in fusion reactors
    New experimental results suggest that sprinkling boron into a tokamak could shield the wall of the fusion vessel and prevent atoms from the wall from getting into the plasma. A new computer modeling framework shows the boron powder may only need to be sprinkled from one location.
  • Nanopillars create tiny openings in the nucleus without damaging cells
    Researchers have created an array of nanopillars that can breach the nucleus of a cell -- the compartment that houses our DNA -- without damaging the cell's outer membrane. This new 'gateway into the nucleus' could open new possibilities in gene therapy, where genetic material needs to be delivered directly into the nucleus, as well as drug delivery and other forms of precision...
  • Using antimatter to detect nuclear radiation
    Discerning whether a nuclear reactor is being used to also create material for nuclear weapons is difficult, but capturing and analyzing antimatter particles has shown promise for monitoring what specific nuclear reactor operations are occurring, even from hundreds of miles away. Researchers have developed a detector that exploits Cherenkov radiation, sensing antineutrinos and ...
  • A new and unique fusion reactor
    As part of the global effort to harness power from fusing plasma, scientists worked on the computer codes, engineering and physics for a new and unique fusion reactor: the SMall Aspect Ratio Tokamak.
  • Researchers measure more detailed data on the 'magic' N=50 neutron shell closure
    Researchers have found new information about the strength of the so-called magic neutron number 50 shell closure in the silver isotope chain. The new more detailed information on the properties of the nuclei will contribute crucial information for refining our understanding of nuclear forces. The research improves state-of-the-art theoretical models and thus benefits the global...
  • Breakthrough in hydrogen research
    Hydrogen is in great demand due to its promising role as a sustainable resource in the energy transition. Researchers have made an important breakthrough in the efficient and cost-effective provision of isotopes. These are the three forms in which hydrogen occurs in nature -- as protium, deuterium or tritium. The team has taken a big step towards realizing its dream of separati...
  • Shedding light on superconducting disorder
    The importance of disorder in physics is only matched by the difficulty to study it. For example, the remarkable properties of high-temperature superconductors are greatly affected by variations in the chemical composition of the solid. Techniques that enable measurements of such disorder and its impact on the electronic properties, such as scanning tunnelling microscopy, work ...
  • Towards the realization of compact and portable nuclear clocks
    The low-energy excited state of thorium-229 (229Th) isotope nucleus has recently gained much attention owing to it being an ideal candidate for ultra-precise nuclear clocks. Building such high-precision clocks requires an acute understanding of the excitation and de-excitation state of the nucleus. In this view, researchers have designed 229Th-doped vacuum ultraviolet (VUV) tra...
  • Hair-thin wire to help simulate cosmic conditions
    Extreme conditions prevail inside stars and planets. The pressure reaches millions of bars, and it can be several million degrees hot. Sophisticated methods make it possible to create such states of matter in the laboratory -- albeit only for the blink of an eye and in a tiny volume. So far, this has required the world's most powerful lasers, and the opportunities for experimen...
  • Quantum researchers cause controlled 'wobble' in the nucleus of a single atom
    Researchers have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom. This electron could be manipulated and read out through the needle of a scanning tunneling microscope. The research offers prospects for storing quantum information inside the nucleus...
