Book Alpha Beta and Gamma Ray Spectroscopy

Download or read book Alpha Beta and Gamma Ray Spectroscopy written by K. Siegbahn and published by Elsevier. This book was released on 2012-12-02 with total page 915 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alpha-, Beta- and Gamma-Ray Spectroscopy Volume 1 offers a comprehensive account of radioactivity and related low-energy phenomena. It summarizes progress in the field of alpha-, beta- and gamma-ray spectroscopy, including the discovery of the non-conservation of parity, as well as new experimental methods that elucidate the processes of weak interactions in general and beta-decay in particular. Comprised of 14 chapters, the book presents experimental methods and theoretical discussions and calculations to maintain the link between experiment and theory. It begins with a discussion of the interaction of electrons and alpha particles with matter. The book explains the elastic scattering of electrons by atomic nuclei and the interaction between gamma-radiation and matter. It then introduces topic on beta-ray spectrometer theory and design and crystal diffraction spectroscopy of nuclear gamma rays. Moreover, the book discusses the applications of the scintillation counter; proportional counting in gases; and the general processes and procedures used in determining disintegration schemes through a study of the beta- and gamma-rays emitted. In addition, it covers the nuclear shell model; collective nuclear motion and the unified model; and alpha-decay conservation laws. The emissions of gamma-radiation during charged particle bombardment and from fission fragments, as well as the neutron-capture radiation spectroscopy, are also explained. Experimentalists will find this book extremely useful.

Available in PDF, EPUB and Kindle. Book excerpt: Internal Conversion Processes documents the proceedings of the International Conference on the Internal Conversion Process held at Vanderbilt University, Nashville, Tennessee on May 10-13, 1965. This compilation discusses the internal conversion theory; experimental methods for the determination of internal conversion coefficients; and conversion electron-gamma directional correlation. Other topics include the application of the internal-external conversion (IEC) method to the lens-type spectrometer; anomalies of E2 conversion coefficients in the deformed-nucleus region; and conversion coefficients of mixed E2-M1 rotational transitions. The anomalous El conversion; internal conversion electrons from primary fission fragments; particle parameters measured in pure transitions; and survey of El transitions in the rare earth region are also discussed in this book. This publication is a good reference for nuclear physicists and researchers conducting work on the various types of measurements that involve internal conversion electrons.

Book Low lying Levels in Some Spherical and Rotational Nuclides by Coulomb Excitation and Radiative Capture of Thermal Neutrons

Download or read book Low lying Levels in Some Spherical and Rotational Nuclides by Coulomb Excitation and Radiative Capture of Thermal Neutrons written by Donald Allan McClure and published by . This book was released on 1969 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The work presented in this dissertation was performed in order to obtain additional information on the level schemes and decay properties of several nuclei in an attempt to explain the observations in terms of an applicable nuclear model. Various nuclear models are discussed in Section II. A general review from the classical point of view of the Coulomb excitation reaction is discussed in Section III and the thermal-neutron-capture reaction is outlined in Section IV. The experimental equipment and procedure is discussed in Section V in which the ramper method of energy determination is outlined. This method allows the measurement of y-ray energies to an accuracy of [approximately] 0.1 keV in many cases and therefore increases the chances for an unambiguous placement of the [gamma]-ray in a level scheme. A method for the accurate determination of the analyzing system dead time is also presented. The exclusive use of Ge(Li) detectors is made in both singles and coincidence [gamma]-ray studies . A series of measurements on the singles and coincidence [gamma]-ray spectra as well as the conversion electron spectra following the decay of 66Ge is presented in Section VI. This nucleus decays primarily by allowed beta transitions permitting the determination of the quantum mechanical parameters of many of the states in 66Ge. This nuclide is expected to exhibit excited states being primarily single-particle in nature. The shell model structure of these states could lead to the occurrence of forbidden M1 transitions and indeed the first excited state of 66Ge does exhibit a retarded M1 transition as reflected in its 21 nsec lifetime. Measurements of the de-excitation [gamma]-rays following Coulomb excitation of the low-lying levels in 105Pd are presented in Section VII. Attempts to describe this nucleus in terms of Nilsson orbitals have been largely unsuccessful. A description of the low-lying levels in terms of the core-excitation model is presented. The agreement between the experimental observations and the predictions of the core-excitation model is somewhat less than satisfying. However, accurate B(E2)[up arrow] transition probabilities are presented which may be compared to a more extensive theoretical treatment. Section VIII discusses the thermal-neutron-capture reaction 186W ([nu, gamma])187W]. Both high-energy and low-energy [gamma]-rays have been observed using both singles and coincidence [gamma]-ray spectroscopic techniques in an attempt to construct an unambiguous level scheme. The resulting low-lying energy levels are discussed in terms of the Nilsson model including the Coriolis band mixing terms. Evidence is presented for the existence of Coriolis mixed states built on the [512]3/2̄−, and [510]1/2− intrinsic states . The results of the model-predicted energy level sequence and [gamma]-ray branching ratios are discussed"--Abstract, leaes ii-iii.

Book Studies in Low Energy Nucler Science

Download or read book Studies in Low Energy Nucler Science written by and published by . This book was released on 1906 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a summary of research projects in the area of low energy nuclear reactions and structure, carried out between 1 January 2003 and 31 December 2005 and supported by U.S. DOE grant number DE-FG03-03NA00074. Cross sections measured with high resolution have been subjected to an Ericson theory analysis to infer information about the nuclear level density. Other measurements were made of the spectral shape of particles produced in evaporation processes; these also yield level density information. A major project was the development of a new Hauser-Feshbach code for analyzing such spectra. Other measurements produced information on the spectra of gamma rays emitted in reactions on heavy nuclei and gave a means of refining our understanding of gamma-ray strength functions. Finally, reactions on light nuclei were studied and subjected to an R-matrix analysis. Cross sections fora network of nuclear reactions proceedingthrough a given compound nucleus shouldgreatly constrain the family of allowed parameters. Modifications to the formalism andcomputer code are also discussed.

Book Physics of Nuclei and Particles

Download or read book Physics of Nuclei and Particles written by Pierre Marmier and published by Academic Press. This book was released on 2013-10-22 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physics of Nuclei and Particles, Volume II explores the prevalent descriptive methods used in nuclear and particle physics, with emphasis on the phenomenological and model-based aspects. The interactions of nuclear particles are discussed, along with nuclear forces and potentials and scattering and reaction models employed in nuclear physics. The nuclear structure and models of the nucleus are also considered. Comprised of four chapters, this volume begins with a review of the characteristics of nucleons and other particles that play a role in nuclear interaction processes in order to gain further insight into the underlying physical problems. Neutron physics, antinucleons, deuteron physics, and two-body nuclear forces are highlighted, together with three- and four- nucleon systems and heavy-ion physics. The next three chapters deal with nuclear forces and potentials, as deduced from nuclear dynamics (scattering and polarization); scattering and reaction models used in nuclear physics; and nuclear models such as the shell model, models of deformed nuclei, and many-body self-consistent models. The book concludes with an analysis of the Brueckner-Bethe-Goldstone theory of nuclear matter. This book will be of interest to physicists.
