Available in PDF, EPUB and Kindle. Book excerpt: An isotope of the element with atomic number 97 has been discovered as a product of the helium-ion bombardment of americium. This isotope decays with the emission of alpha-particles of maximum energy 6.72 Mev (30 percent) and it emits lower energy alpha-particles of energies 6.55 Mev (53 percent) and 6.20 Mev (17 percent). The half-life of this isotope is 4.6 hours and it decays primarily by electron capture with about 0.1 percent branching decay by alpha-particle emission. The mass number is probably 243 as indicated by chemical separation of the alpha-particle and electron-capture daughters. The name berkelium, symbol Bk, is proposed for element 97. The chemical separation of element 97 from the target material and other reaction products was made by combinations of precipitation and ion exchange adsorption methods making use of its anticipated (III) and (IV) oxidation states and its position as a member of the actinide transition series. The distinctive chemical properties made use of in its separation and the equally distinctive decay properties of the particular isotope constitute the principal evidence for the new element.

Book excerpt: During his distinguished career spanning more than 50 years, Nobel laureate (Chemistry) Glenn T Seaborg published over 500 works. This volume puts together about 100 of his selected papers. The papers are divided into five categories. Category I consists of papers which detail the discovery of 10 transuranium elements and numerous heavy isotopes of special importance. Category II papers describe the discovery of a number of isotopes which became the workhorses of nuclear medicine or found other applications. Papers in Category III describe how the chemical properties of transuranium elements were originally determined, how chemistry is applied in nuclear sciences, and other chemical investigations, including early work done with the great chemist G N Lewis. Papers in Category IV cover radioactive decay chains and nuclear systematics. Lastly, papers in Category V illustrate how the powerful methods of chemistry are used to explain nuclear reactions in low, intermediate and high energy nuclear physics. Contents:New Elements, New Isotopes, Actinide ConceptEarly Radioactive Isotopes, Nuclear Medicine, and Other Practical ApplicationsEmphasis on ChemistryDecay Chains, Nuclear Systematics, More IsotopesChemical and Radiochemical Probes for Interpretation of Nuclear Reactions Readership: Chemists. keywords: “In addition to research papers, reviews, reports, and addresses make the collection more colorful and very interesting to read. They are also testimony to the wide scope of Seaborg's interest and his outstanding abilities as a communicator. The foundation of all is, however, his seminal discoveries. For he is a true pioneer blessed with a far-seeing vision.” The Chemical Intelligencer

Book excerpt: Definite identification has been made of an isotope of the element with atomic number 98 through the irradiation of Cm242 with about 35-Mev helium ions in the Berkeley Crocker Laboratory 60-inch cyclotron. The isotope which has been identified has an observed half-life of about 45 minutes and is thought to have the mass number 244. The observed mode of decay of 98244 is through the emission of alpha-particles, with energy of about 7.1 Mev, which agrees with predictions. Other considerations involving the systematics of radioactivity in this region indicate that it should also be unstable toward decay by electron capture. The chemical separation and identification of the new element was accomplished through the use of ion exchange adsorption methods employing the resin Dowex-50. The element 98 isotope appears in the eka-dysprosium position on elution curves containing berkelium and curium as reference points--that is, it precedes berkelium and curium off the column in like manner that dysprosium precedes terbium and gadolinium. The experiments so far have revealed only the tripositive oxidation state of eka-dysprosium character and suggest either that higher oxidation states are not stable in aqueous solutions or that the rates of oxidation are slow. The successful identification of so small an amount of an isotope of element 98 was possible only through having made accurate predictions of the chemical and radioactive properties.

Available in PDF, EPUB and Kindle. Book excerpt: Actinides in Perspective presents in proceedings of the Actinides-1981 Conference held in Pacific Grove, California, USA on September 10-15, 1981. The book contains papers on the different aspect of the physics and chemistry of the actinides. The text includes papers on the history of the discovery of the transplutonium elements; the photoemission techniques; and the neutron scattering studies of the actinides. The new elements in the transfermium region; the isotope identification in the transfermium region by ?-? correlation after in-flight-separation; and the fission properties of the actinides are also considered. The book further tackles papers on the status of superheavy element research; the single crystal preparation of actinides and actinide compounds; and the preparation of transplutonium metals and compounds, protactinium metal and compounds, and actinide metals. The text also includes papers on the complex oxide systems of the actinides; thermodynamic properties of the actinides; and the chemical and physicochemical properties of actinide organometallic compounds.
