Book excerpt: The decay scheme of a 4.2 second neutron emitter has been investigated in detail. Chemical and physical evidence shows that it is N17, which emits beta rays to a broad excited state of O17, which then breaks up into a neutron plus O16. The energy spectrum of the neutrons is determined by measuring the energies of the O16 recoils in a proportional counter. The neutrons have a most probable energy of 0.9 Mev, a 'half width' of less than .5 Mev, and an upper limit of about 2 Mev. [beta]-recoil coincidences are observed, as predicted by the Bohr-Wheeler theory, and the [beta]-ray energy is measured by absorption. The beta rays in coincidence with neutrons have an upper limit of 3.7 ± 0.2 Mev. Beta-rays directly to the ground stat of O17 are not observed because of high background effects, but should have an energy of 8.7 Mev. Some evidence is presented to show that energy is conserved in the [beta]-n transition through the broad excited state in O17.

Download or read book Nondestructive Activation Analysis written by S. Amiel and published by Elsevier. This book was released on 2012-12-02 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies in Analytical Chemistry, 3: Nondestructive Activation Analysis focuses on the reactions, principles, methodologies, and approaches involved in nondestructive activation analysis. The selection first offers information on irradiation, measurement and techniques, and manual and computerized data processing in activation analysis. Discussions focus on result computation with Nal(Tl) and Ge(Li) data, analysis of gamma-ray spectra, X-ray, spectrometry, neutron counting in activation analysis, neutron sources, and measurement of very short-lived nuclides. The book then examines applications, including biomedical sciences, geo- and cosmochemistry, applications of trace element analysis to studies of the atmospheric environment, and high purity materials, standards, and reference materials. The text discusses the applications of nondestructive activation analysis to archaeology, industry, and forensics. The selection is a vital reference for researchers wanting to explore nondestructive activation analysis.

Download or read book Analytical Methods for Nonproliferation written by Edward C. Morse and published by Springer. This book was released on 2016-04-04 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to be used as a textbook and research reference for the field of nuclear nonproliferation. The book is primarily technical and focussed on methods of detecting clandestine nuclear material that might be illicitly transported. The book also touches on nuclear forensics, i.e. methods for identification, attribution, and establishment of transport pathways for illicit nuclear material. Also covered are topics of methods used for arms control and treaty verification, and an assessment of technologies under development for all of the above. A description of the government and international agencies involved in nuclear terrorism prevention, nuclear safeguards, and arms control is also included.
Download or read book The Discovery of Isotopes written by Michael Thoennessen and published by Springer. This book was released on 2016-06-02 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the exciting discovery of every isotope observed on earth to date, which currently numbers some 3000. The discoveries are arranged in chapters according to the observation techniques or production methods. Each chapter contains tables listing the first authors of the first publication as well as details about the production and detection methods used. At the end, a comprehensive table lists all isotopes sorted by elements. The book is based on individual paragraphs for each isotope, which were published over the last few years as separate articles in the journal “Atomic Data and Nuclear Data Tables”. The work re-evaluates all prior assignments judging them with a uniform set of criteria. In addition, the author includes over 100 new isotopes which have been discovered since the articles published. This book is a source of information for researchers as well as enthusiastic laymen alike. From the prepublication review: “The explanations focus on the essentials, which makes the various chapters pleasingly compact. The phrasing is well understandable also for non-experts. This makes the book easy to read, even thrilling. I have to confess that parts of the manuscript I was even reading as an evening lecture in the bed, so exciting was the history of isotope discoveries.” Sigurd Hofmann, Helmholtz Professor at GSI Darmstadt, Germany, and a leading expert in superheavy nuclei
