Book excerpt: The production of neutron deficient actinide isotopes in heavy ion reactions was studied using alpha, gamma, x-ray, and spontaneous fission detection systems. A new isotope of berkelium, 242Bk, was produced with a cross-section of approximately 10 .mu.b in reactions of boron on uranium and nitrogen on thorium. It decays by electron capture with a half-life of 7.0 +- 1.3 minutes. The alpha-branching ratio for this isotope is less than 1% and the spontaneous fission ratio is less than 0.03%. Studies of (Heavy Ion, pxn) and (Heavy Ion, .cap alpha.xn) transfer reactions in comparison with (Heavy ion, xn) compound nucleus reactions revealed transfer reaction cross-sections equal to or greater than the compound nucleus yields. The data show that in some cases the yield of an isotope produced via a (H.I., pxn) or (H.I., .cap alpha.xn) reaction may be higher than its production via an xn compound nucleus reaction. These results have dire consequences for proponents of the ''Z1 + Z2 = Z/sub 1+2/'' philosophy. It is no longer acceptable to assume that (H.I., pxn) and (H.I., .cap alpha.xn) product yields are of no consequence when studying compound nucleus reactions. No evidence for spontaneous fission decay of 228Pu, 23°Pu, 232Cm, or 238Cf was observed indicating that strictly empirical extrapolations of spontaneous fission half-life data is inadequate for predictions of half-lives for unknown neutron deficient actinide isotopes.

Available in PDF, EPUB and Kindle. 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.
Download or read book Handbook of Nuclear Chemistry written by Attila Vértes and published by Springer Science & Business Media. This book was released on 2003 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Impressive in its overall size and scope, this five-volume reference work provides researchers with the tools to push them into the forefront of the latest research. The Handbook covers all of the chemical aspects of nuclear science starting from the physical basics and including such diverse areas as the chemistry of transactinides and exotic atoms as well as radioactive waste management and radiopharmaceutical chemistry relevant to nuclear medicine. The nuclear methods of the investigation of chemical structure also receive ample space and attention. The international team of authors consists of 77 world-renowned experts - nuclear chemists, radiopharmaceutical chemists and physicists - from Austria, Belgium, Germany, Great Britain, Hungary, Holland, Japan, Russia, Sweden, Switzerland and the United States. The Handbook is an invaluable reference for nuclear scientists, biologists, chemists, physicists, physicians practicing nuclear medicine, graduate students and teachers - virtually all who are involved in the chemical and radiopharmaceutical aspects of nuclear science. The Handbook also provides for further reading through its rich selection of references.
