Researchers have shown that there are two coexisting, competing quantum shapes at low energy in 98Kr, never before seen for neutron-rich Kr isotopes. The team also showed that these isotopes experience a gentle onset of deformation with added neutrons, in sharp contrast with neighboring isotopes of rubidium, strontium, and zirconium, which change shapes suddenly at neutron number 60. This study marks a decisive step towards an understanding of the limits of this quantum phase transition region, and was published in Physical Review Letters.
Fusion power has the potential to provide clean and safe energy that is free from carbon dioxide emissions. However, imitating the solar energy process is a difficult task to achieve. Two young plasma physicists at Chalmers University of Technology have now taken us one step closer to a functional fusion reactor. Their model could lead to better methods for decelerating the runaway electrons, which could destroy a future reactor without warning.
Collectors have become increasingly interested in weapons from ancient Asia and the Middle East. Attempting to fight forgeries, physicists are now adding their imaging power to authenticate these weapons. In a study published in EPJ Plus, an Italian team, working with the Wallace Collection, London and the Neutron Imaging team at the Helmholtz Zentrum Berlin, has demonstrated the usefulness of such a combined imaging approach to help museum curators in their quest to ensure authenticity.
A research team, led by South Korea's Ulsan National Institute of Science and Technology has proposed a new method that might be used to detect nuclear hazards from up to a few hundred meters away.
A UCSB physicist and colleagues review three experiments that hint at a phenomenon beyond the Standard Model of particle physics.
Material developed at Dartmouth College scrubs iodine from water for the first time and could hold the key to cleaning nuclear accidents.
Rochester Institute of Technology researcher Richard O'Shaughnessy and collaborators reanalyzed the merging black holes detected by LIGO (Laser Interferometer Gravitational Wave Observatory) on Dec. 26, 2016, and drew new insights about what happens when massive stars die and transform into black holes.
Study offers new theoretical approaches to explain and predict high-energy nuclear collisions experiments; Computer simulations performed enabled the researchers to make predictions to test, validate or correct the model.
RIT scientists working with the LIGO Scientific Collaboration measured and interpreted the spin and alignment of a newly formed black hole detected on Jan. 4 by LIGO. The RIT team also simulated the gravitational wave signal produced in the collision that formed the new black hole.
MIT researchers have developed a much faster, non-contact method of studying how materials change in a high-radiation environment, such as inside a nuclear reactor.
