  • The Argonne Tandem Linac Accelerator System (ATLAS) is the world's first superconducting linear accelerator for heavy ions at energies in the vicinity of the Coulomb barrier. (anl.gov)
  • Physics
  • Argonne's Physics Division maintains several key facilities dedicated to expanding our knowledge of and ability to manipulate different elemental isotopes. (anl.gov)
  • water
  • The study, titled Concomitant variability in high-latitude aerosols, water isotopes and the hydrologic cycle , utilized data provided by Joe McConnell, Ph.D., director of DRI's Ultra-Trace Chemistry Laboratory in Reno, Nev. (dri.edu)
  • The correlation between the thing that records the climate (the water isotope ratios) and these aerosols is extremely good," he continued. (dri.edu)
  • They also thought they had detected gamma radiation characteristic of neutrons passing through water, but these results later had to be retracted. (scientificamerican.com)
  • concentration
  • When climate scientist Bradley Markle, at UC Santa Barbara's Earth Research Institute, spotted a correlation between the ratios of heavy molecules and the concentration of particulate matter in the Antarctic ice cores he was studying, he immediately set out to uncover the deeper connection. (dri.edu)
  • Scientists noticed that ice layers with higher ratios of heavy isotopes also contained a greater concentration of trapped aerosols. (dri.edu)
  • Hence, if one species fixes nitrogen from the air and if neighbouring plants take up this additional nitrogen, then the leaves of these neighbouring plants should also reveal a higher concentration of heavy nitrogen isotopes. (eurekalert.org)
  • atomic
  • Therefore, whereas the importance of the proton and the electron is very clear to anyone who studies atomic behavior, neutrons, on the other hand, might seem at first glance as though they are only "along for the ride. (encyclopedia.com)
  • magnetic
  • BBND results show the overall neutron environment at the ISS orbital altitude is influenced by highly energetic galactic cosmic rays, except in the South Atlantic Anomaly (SAA) region where protons trapped in the Earth's magnetic field cause a more severe neutron environment. (wikiversity.org)

  • Curium is used in production of heavier actinides and of the 238 Pu radionuclide for power sources in artificial pacemakers . (wikipedia.org)
  • extremely
  • The He-3 isotope is extremely rare on Earth, but exists in abundance on the Moon, and the Chinese leadership has already begun an ambitious program to acquire it. (spacesafetymagazine.com)
  • half life
  • A joint effort by the researchers from the Lawrence Berkeley National Laboratory, the Argonne National Laboratory, and the Los Alamos National Laboratory resulted in the chemical isolation and identification of the 20 h half-life isotope 255 Fm (Ghiorso et al . (springer.com)
