Wavelengths, Transition Probabilities, and Energy Levels for the Spectra of Barium „Ba III Through Ba LVI… Wavelengths, Transition Probabilities, and Energy Levels for the Spectra of Barium „Ba III through Ba LVI… J. E. Sansonettia… and J. J. Curry National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA ͑Received 3 May 2010; accepted 4 May 2010; published online 19 November 2010͒ Energy levels, with designations and uncertainties, have been compiled for the spectra of barium ͑Z=56͒ ions from doubly ionized to hydrogenlike. Wavelengths with classifi- cations, intensities, and transition probabilities are also tabulated. In addition, ground states and ionization energies are listed. For many ionization stages experimental data are available; however, for those for which only theoretical calculations or fitted values exist, these are reported. There are a few ionization stages for which only a calculated ioniza- tion potential is available. © 2010 by the U.S. Secretary of Commerce on behalf of the United States.

  • 6. Potential for Human Exposure
    CESIUM 125 6. POTENTIAL FOR HUMAN EXPOSURE 6.1 OVERVIEW Cesium has been identified in at least 8 of the 1,636 hazardous waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) (HazDat 2003). It was reported that 134Cs has been found in at least 3 of the 1,636 current or former NPL sites and 137Cs has been detected in at least 23 of the 1,636 current or former NPL sites. However, the number of sites evaluated for cesium is not known. The frequency of these sites can be seen in Figures 6-1, 6-2, and 6-3. Of these sites, none are located in the Commonwealth of Puerto Rico. Naturally-occurring cesium and cesium minerals consist of only one stable isotope, 133Cs. Cesium occurs in the earth's crust at low concentrations. Granites contain an average cesium concentration of about 1 ppm and sedimentary rocks contain about 4 ppm (Burt 1993). Higher concentrations are found in lepidolite, carnallite, muscovite, beryl, spodumene, potassium feldspars, leucite, petalite, and related minerals. The most important source of commercial cesium is the mineral pollucite, which usually contains about 5–32% Cs2O (Burt 1993). The largest deposits of pollucite are located in Manitoba, Canada and account for about two-thirds of the world’s known supply. Smaller deposits are located in Zimbabwe, Namibia, Brazil, Scandinavia, Czechoslovakia, and the United States. Continental dust and soil erosion are the main emission sources of naturally occurring cesium present in the environment. Cesium is also released to the environment as a result of human activities.

    To appear in Space Exploration Research, Editors: J. H. Denis, P. D. Aldridge Chapter 7 (Nova Science Publishers, Inc.) ISBN: 978-1-60692-264-4 Fingerprints of a Local Supernova Oliver Manuela and Hilton Ratcliffeb a Nuclear Chemistry, University of Missouri, Rolla, MO 65401 USA b Climate and Solar Science Institute, Cape Girardeau, MO 63701 USA ABSTRACT. The results of precise analysis of elements and isotopes in meteorites, comets, the Earth, the Moon, Mars, Jupiter, the solar wind, solar flares, and the solar photosphere since 1960 reveal the fingerprints of a local supernova (SN)—undiluted by interstellar material. Heterogeneous SN debris formed the planets. The Sun formed on the neutron (n) rich SN core. The ground-state masses of nuclei reveal repulsive n-n interactions that can trigger axial n-emission and a series of nuclear reactions that generate solar luminosity, the solar wind, and the measured flux of solar neutrinos. The location of the Sun's high-density core shifts relative to the solar surface as gravitational forces exerted by the major planets cause the Sun to experience abrupt acceleration and deceleration, like a yoyo on a string, in its orbit about the ever-changing centre-of-mass of the solar system. Solar cycles (surface magnetic activity, solar eruptions, and sunspots) and major climate changes arise from changes in the depth of the energetic SN core remnant in the interior of the Sun.

  • From the Natural Transmutations of Uranium to Its Artificial Fission
    O T T O H AH N From the natural transmutations of uranium to its artificial fission Nobel Lecture, December 13, 1946 The year 1946 marked a jubilee in the history of the chemical element, ura- nium. Fifty years earlier, in the spring of 1896, Henri Becquerel had discov- ered the remarkable radiation phenomena of this element, which were at that time grouped together under the name of radioactivity. For more than 100 years, uranium, discovered by W. H. Klaproth in 1789, had had a quiet existence as a somewhat rare but not particularly interesting element. After its inclusion in the Periodic System by D. Mendeleev and Lothar Meyer, it was distinguished from all the other elements in one partic- ular respect: it occupied the highest place in the table of the elements. As yet, however, that did not have any particular significance. We know today that it is just this position of uranium at the highest place of the then known chemical elements which gives it the important properties by which it is distinguished from all other elements. The echo of Becquerel’s fundamental observations on the radioactivity of uranium in scientific circles was at first fairly weak. Two years later, how- ever, they acquired an exceptional importance when the Curies succeeded in separating from uranium minerals two active substances, polonium and ra- dium, of which the latter appeared to be several million times stronger than the same weight of uranium. It was only a few years before the first surprising property of this "ra- diating" substance was explained.

  • Meteoritic Barium and Anomalies Cerium Versus in Meteoritic The
    Geochemical Journal, Vol. 13, pp. 137 to 140, 1979 137 NOTE Meteoritic barium and cerium versus the general isotopic anomalies in meteoritic xenon P. K. KURODA Department of Chemistry, University of Arkansas, Fayetteville, Arkansas 72702 U.S.A. (Received March 10, 1979) The difference in the isotopic compositions of barium from some meteorites and from the terrestrial barium is explained as due to the alteration of the isotopic ratios by a combined effect of mass-dependent fractionation, neutron-capture and cosmic-ray irradiation processes, which took place prior to and during the period of formation of the solar system. The abundances of 134Ba and ' 35 Ba in the meteorite Bruderheim seem to be slightly enhanced due to the decays of 2.06-year ' 34Cs and 2.3 X 106-year 13 5Ba A small difference in the isotopic compositions of cerium in the Bruderheim meteorite and the terrestiral sample can also be attributed to neutron-capture processes, which occurred during an early irradiation period. It is shown that the barium and xenon isotopic anomalies observed in meteorites are closely related to each other. INTRODUCTION Sixteen years later, MCCULLOCHand WASSER BURG (1978) found isotopic anomalies for Soon after the discovery of the so-called barium and neodymium in two inclusions from special and general anomalies in meteoritic the Allende meteorite.

  • Isotopic Fractionation of Barium in Shale and Produced Water from the Appalachian Basin, Usa
    ISOTOPIC FRACTIONATION OF BARIUM IN SHALE AND PRODUCED WATER FROM THE APPALACHIAN BASIN, USA by Zachary Garrison Tieman B.S. Earth Science, George Mason University, 2011 Submitted to the Graduate Faculty of the Kenneth P. Dietrich School of Arts and Sciences in partial fulfillment of the requirements for the degree of Master of Science University of Pittsburgh 2017 UNIVERSITY OF PITTSBURGH KENNETH P. DIETRICH SCHOOL OF ARTS AND SCIENCES This thesis was presented by Zachary Garrison Tieman It was defended on November 30, 2017 and approved by Rosemary Capo, Associate Professor, Department of Geology and Environmental Science Charles E. Jones, Senior Lecturer, Department of Geology and Environmental Science Josef Werne, Professor, Department of Geology and Environmental Science Thesis Advisor: Brian Stewart, Associate Professor, Department of Geology and Environmental Science ii ISOTOPIC FRACTIONATION OF BARIUM IN SHALE AND PRODUCED WATER FROM THE APPALACHIAN BASIN, USA Zachary Garrison Tieman, MS University of Pittsburgh, 2017 Waters co-produced with oil and gas are often rich in barium (Ba), which can cause scale formation and fouling of wells, especially in unconventional Marcellus Shale gas wells. To address the source of barium in these produced waters, Ba isotope ratios were determined on returned water samples from a Marcellus Shale gas well in West Virginia and other oil- and gas- producing units in Pennsylvania, as well as on exchangeable and carbonate Ba from core samples. This study presents the first known measurements of barium isotopes in produced waters from conventional and unconventional wells and from shale core material. Previous studies have shown that the lighter isotopes of Ba are preferentially fractionated into solid aqueous Ba-rich minerals (e.g., barite, BaSO4, and witherite, BaCO3), and that Ba isotopes can be fractionated by biological and cation exchange processes.

Its name derives from the Greek word barys, meaning "heavy." A silvery-white, soft, ductile and somewhat malleable metal, barium gives off a green color in flame. It is extremely reactive and readily reacts with water, ammonia, halogens, oxygen and most acids. Barium metal reacts exothermically with oxygen at ambient temperatures, forming barium oxide; the reaction is especially violent when the metal is present in powder form. Barium also reacts violently with water, forming barium hydroxide and liberating hydrogen. It reacts violently with dilute acids, evolving hydrogen. Barium is a strong reducing agent. It reduces oxidizing agents, reacting violently. It also combines with several metals — including aluminum, zinc, lead and tin — forming a wide range of intermetallic compounds and alloys. The most important use of barium is as a scavenger in electronic tubes. The metal, often in powder form or as an alloy with aluminum, is employed to remove the last traces of gases from vacuum and television picture tubes.
