  • neutron
  • The most interesting short-lived isotopes synthesized during a recent experiment at RIKEN's Radioactive Isotope Beam Factory (RIBF) were calcium-59 and calcium-60, which are now the most neutron -laden calcium isotopes known to science. (phys.org)
  • tracers
  • They use naturally occurring isotopes as tracers to find out where groundwater comes from, if it is recent or old, if it is being recharged or polluted and how it travels. (iaea.org)
  • Mass spectroscopes also are employed to separate isotopes and to measure the abundance of concentrated isotopes when used as tracers in chemistry , biology, and medicine . (britannica.com)
  • sulfur
  • Researchers from Michigan State University and the RIKEN Nishina Center in Japan discovered eight new rare isotopes of the elements phosphorus, sulfur, chlorine, argon, potassium, scandium and, most importantly, calcium. (phys.org)
  • Two of the other new isotopes of sulfur and chlorine, S-49 and Cl-52, were not predicted to exist by a number of models that paint a lower resolution picture of nuclei. (phys.org)
  • species
  • were presumably rapid, resulting in discrimination against the heavy isotope in those species. (thefreedictionary.com)
  • The name isotope (from the Greek for "same place") was suggested by the British chemist Frederick Soddy in 1913 for these different radioactive forms of the same chemical species, because they could be classified in the same place in the periodic table of the elements . (britannica.com)
  • plutonium
  • To produce good-quality weapons-grade plutonium--with a concentration of the most-important heavy isotope (Pu240)--a short "burnup" fuel cycle is employed, meaning that the reactor fuel rods are removed earlier than they would be if the reactor was utilized to produce electricity. (thefreedictionary.com)
  • Only one isotope of uranium ( 235 U) and one of plutonium ( 239 Pu) can conveniently be used to manufacture a weapon (I'll explain what the numbers mean below). (ferret.com.au)
  • metals
  • Langway-IBMED-50 purifies and removes toxic products from body, salts of heavy metals and other harmful substances , - informed Interfax Chief Medical Doctor - Director of the Institute of Biological Medicine (IBMED), Academician Y. Bloshansky. (rexresearch.com)
  • data
  • Since early 2016, Argentinian isotope hydrologists have been gathering and interpreting data from two strategic regions with the help of the IAEA. (iaea.org)
  • science
  • The science behind this is called isotope hydrology - a discipline that, according to expert Solomon, "is one of the most powerful, trustworthy tools available to assess groundwater thoroughly. (iaea.org)
  • ones
  • Some even heavier ones might barely exist fractions of a second before disintegrating. (phys.org)
  • rare
  • Creating and identifying rare isotopes is the nuclear-physics version of a formidable needle-in-a-haystack problem. (phys.org)
  • In the resulting debris of the collision, with a minuscule chance, a rare isotope such as calcium-60 is formed. (phys.org)
  • body
  • Eiler's group has previously used such a "clumped isotope" technique to determine the body temperatures of dinosaurs, ground temperatures in ancient East Africa, and surface temperatures of early Mars. (redorbit.com)
