Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems. However, these methods reach their limits when so-called sign oscillations occur. An international team of researchers, including scientists from the Facility for Rare Isotope Beams, have solved this problem using the new method of wavefunction matching.
Using ultrafast, atom-at-a-time methods, researchers are starting to explore the unmapped region of the periodic table and finding it as fantastical as any medieval cartographer’s imaginings. At the Facility for Rare Isotope Beams in Michigan, a new high-energy beam promises to give further insights into rapid neutron capture by packing more neutrons into isotopes than ever before possible.
The U.S. Department of Energy Office of Science (DOE-SC) posted a highlight titled “The Facility for Rare Isotope Beams observes five never-before-seen isotopes” about how the Facility for Rare Isotope Beams (FRIB) discovered five never-before-seen heavy element isotopes: thulium-182 and 183, ytterbium-186 and 187, and lutetium-190. The authors of the publication are from FRIB, the Institute for Basic Science, and RIKEN Nishina Center for Accelerator-Based Science. Each year, scientists publish thousands of research findings in the scientific literature. About 200 of these are selected annually by their respective program areas in DOE-SC as publication highlights of special note.
An international research team at the Facility for Rare Isotope Beams (FRIB) at Michigan State University has successfully created five new isotopes, bringing the stars closer to Earth. The isotopes—known as thulium-182, thulium-183, ytterbium-186, ytterbium-187, and lutetium-190—were reported 15 February in the journal Physical Review Letters.
Boosted by the £3.4m FRIB Accelerated-beams for Understanding Science and Technology (FAUST) project, funded by the UK Research and Innovation’s Science and Technology Facilities Council, researchers from the University of Surrey will create detectors for the new GRETA gamma-ray array. This array is part of Michigan State University’s $730 million FRIB particle accelerator.
