Annual Report 2019 Annual Report 2019 Laboratory of Radiochemistry Cover The Laboratory of Radiochemistry operates two integral neutron irradiation facilities at the Swiss Spallation Source SINQ, namely the NAA and PNA facilities. Both are run by our Neutron Irradiation Service (NIS), which irradiates samples for PSI-based users and outside partners for the purpose of material sciences or isotope production. Furthermore, our laboratory uses the SINQ Gas-Jet system for tracer experiments, such as needed in preparation of studies with transactinide elements (Z > 103). The core of this setup is a 235U-target installed inside SINQ itself. Both installation underwent substantial revision and upgrade works during the long SINQ-shutdown 2019/2020 The photographs show Alexander Vögele and Dominik Herrmann, members of the Heavy Elements group (NES), and Christoph Stettler of the Control Systems group (LOG) during their works at the NAA/PNA facilities as well as with the SINQ Gas-Jet system.

  • CHEMISTRY for the Bottom of the Periodic Table
    http://cyclotron.tamu.edu CHEMISTRY for the Bottom of the Periodic Table Techniques to investigate chemical properties of superheavy elements lead to improved methods for separating heavy metals THE SCIENCE The chemical properties of superheavy element 113, nihonium, are almost completely unknown, so a team of researchers from the Cyclotron Institute at Texas A&M University and the Institut Pluridisciplinaire Hubert Curien in France are developing techniques that could be used to study this fleeting element. As part of that effort, they are comparing the properties of nihonium to the chemically similar elements indium and thallium; to do so, the team studied the separation of these two elements using a new class of designer molecules called ionic liquids. THE IMPACT Measuring the chemical properties of nihonium and other superheavy elements will increase our understanding of the principles that control the Periodic Table. Comparing the data from nihonium to results for similar elements, obtained using the team’s fast, efficient, single-step process, reveals trends that arise from the structure of the Periodic Table.

  • The Histories Hidden in the Periodic Table
    The Histories Hidden in the Periodic Table From poisoned monks and nuclear bombs to the “transfermium wars,” mapping the atomic world hasn’t been easy. By Neima Jahromi 6:00 A.M. As element hunters have become element makers, the periodic table’s meaning has changed. It now describes what is possible, in addition to what merely exists. Illustration by Ilya Milstein The story of the fifteenth element began in Hamburg, in 1669. The unsuccessful glassblower and alchemist Hennig Brandt was trying to find the philosopher’s stone, a mythical substance that could turn base metals into gold. Instead, he distilled something new. It was foamy and, depending on the preparation, yellow or black. He called it “cold fire,” because it glowed in the dark. Interested parties took a look; some felt that they were in the presence of a miracle. “If anyone had rubbed himself all over with it,” one observer noted, “his whole figure would have shone, as once did that of Moses when he came down from Mt. Sinai.” Robert Boyle, the father of modern chemistry, put some on his hand and noted how “mild and innocent” it seemed. Another scientist saw particles in it twinkling “like little stars.” At first, no one could figure out what the Prometheus of Hamburg had stolen. After one of Brandt’s confidants provided a hint—the main ingredient was “somewhat that belong’d to the Body of Man”—Boyle deduced that he and his peers had been smearing themselves with processed urine. As the Cambridge chemist Peter Wothers explains in his new history of the elements, “Antimony, Gold, and Jupiter’s Wolf” (Oxford), Brandt’s recipe called for a ton of urine.

  • Superheavy Elements: Existence, Classification and Experiment
    UDC 541.2 Superheavy elements: existence, classification and experiment V.A.Kostyghin1, V.M.Vaschenko2, Ye.A.Loza2 1 "Akvatekhinzhiniring", Cherkassy, Ukraine, e-mail:[email protected] 2 State Ecological academy for post-graduate education and management, Kyiv, Ukraine, e-mail:[email protected] This paper proposes spatial periodic table developed based on classic electron shell structure model. The periodic table determines location and chemical properties of superheavy elements. 14 new long-living superheavy elements found by Proton-21 laboratory and one long-living superheavy element found by A.Marinov were identified. Introduction At present there are 118 elements known [1]. However, there are only 104 of them well-studied. The superheavy nuclei existence problem and also nuclones collective states problems (super-nuclei, nuclear associations, multi-nuclei clusters, nuclear condensate etc.) long ago have become subject of experimental and theoretical research [2-7]. This problem is specially important for modern astrophysical concepts [8-10]. The main branch of experimental research of superheavy nuclei isotopes and exotic isotopes of light nuclei is a new elements synthesis by different accelerator with latter investigation of nuclei collision results. However this method has two important and unsolved problems [11, 12]. The first one is the excess energy of the synthesized nucleus. The energy required to overcome the Coulomb barrier during the nuclei collision transforms 1 into internal energy of the newly formed nucleus and it is usually enough for instant nuclei fission, because the internal clusters of the nuclei have energy over Coulomb barrier. This leads to a very complex experimental task of "discharge" of excess energy by high-energy particle radiation - gamma-quantum, neutron, positron, proton, alpha-particle [13] etc.

Superheavy elements are created in the laboratory by the fusion of two heavy nuclei. The large Coulomb repulsion that makes superheavy elements decay also makes the fusion process that forms them very unlikely. Instead, after sticking together for a short time, the two nuclei usually come apart, in a process called quasifission. Mass-angle distributions give the most direct information on the characteristics and time scales of quasifission. A systematic study of carefully chosen mass-angle distributions has provided information on the global trends of quasifission. Large deviations from these systematics reveal the major role played by the nuclear structure of the two colliding nuclei in determining the reaction outcome, and thus implicitly in hindering or favouring superheavy element production. Superheavy elements (SHE) are formed by heavy-ion fusion reactions. Their cross sections are significantly suppressed [1] by the quasifission process [2].

  • Experimental Search for Superheavy Elements
    THE HENRYK NIEWODNICZAŃSKI INSTITUTE OF NUCLEAR PHYSICS POLISH ACADEMY OF SCIENCES UL. RADZIKOWSKIEGO, 31-342 KRAKÓW, POLAND WWW.IFJ.EDU.PL/PUBL/REPORTS/2008/ KRAKÓW, DECEMBER 2008 REPORT No. 2019/PL Experimental search for superheavy elements Andrzej Wieloch* Habilitation thesis (prepared in March 2008) *M. Smoluchowski Institute of Physics, Jagiellonian University. Reymonta 4. 30-059 Kraków, e-mail: [email protected] Abstract This work reports on the experimental search for superheavy elements (SHE). Two types of approaches for SHE production are studied i.e.: "cold" fusion mech­ anism and massive transfer mechanism. First mechanism was studied, in normal and inverse kinematics, by using Wien filter at the GANIL facility. The production of elements with Z=106 and 108 is reported while negative result on the synthesis of SHE elements with Z=114 and 118 was received. The other approach i.e. re­ actions induced by heavy ion projectiles (e.g.:172Yb. 197Au) on fissile target nuclei (e.g.: 2S8U., 2S2Th) at near Coulomb barrier incident energies was studied by using superconducting solenoid installed in Texas A&M University. Preliminary results for the reaction 197 Au(7.5MeV/u) -f 232Th are presented where three cases of the possible candidates for SHE elements were found. A dedicated detection setup for such studies is discussed and the detailed data analysis is presented. Detection of al­ pha and spontaneous fission radioactive decays is used to unambiguously identify the atomic number of SHE. Special statistical analysis for a very low detected number of a decays is applied to check consistency of the a radioactive chains.
