It has been suggested in the past that special numbers of neutrons or protons in the nucleus form a particularly stable configuration.p1s The complete evidence for this has never been summarized, nor is it generally recognized how convincing this evidence is. That 20 neutrons or protons (Ca{sup40}) form a closed shell is predicted by the Hartree model. A number of calculations support this fact.p2s These considerations will not be repeated here. In this paper, the experimental facts indicating a particular stability of shells of 50 and 82 protons and of 50, 82, and 126 neutrons will be listed.
This book is aimed at enabling the reader to obtain a working knowledge of the nuclear shell model and to understand nuclear structure within the framework of the shell model. Attention is concentrated on a coherent, self-contained exposition of the main ideas behind the model with ample illustrations to give an idea beyond formal exposition of the concepts. Since this text grew out of a course taught for advanced undergraduate and first-year graduate students in theoretical nuclear physics, the accents are on a detailed exposition of the material with step-by-step derivations rather than on a superficial description of a large number of topics. In this sense, the book differs from a number of books on theoretical nuclear physics by narrowing the subject to only the nuclear shell model. Most of the expressions used in many of the existing books treating the nuclear shell model are derived here in more detail, in a practitioner's way. Due to frequent student requests I have expanded of detail in order to take away the typical phrase " . . . after some the level simple and straightforward algebra one finds . . . ". The material could probably be treated in a one-year course (implying going through the problem sets and setting up a number of numerical studies by using the provided computer codes). The book is essentially self-contained but requires an introductory course on quantum mechanics and nuclear physics on a more general level.
This book provides an introductory course on Nuclear and Particle physics for undergraduate and early-graduate students, which the author has taught for several years at the University of Zurich. It contains fundamentals on both nuclear physics and particle physics. Emphasis is given to the discovery and history of developments in the field, and is experimentally/phenomenologically oriented. It contains detailed derivations of formulae such as 2- 3 body phase space, the Weinberg-Salam model, and neutrino scattering. Originally published in German as 'Kern- und Teilchenphysik', several sections have been added to this new English version to cover very modern topics, including updates on neutrinos, the Higgs boson, the top quark and bottom quark physics. - Prové de l'editor.
This book provides the first graduate-level, self-contained introduction to recent developments that lead to the formulation of the configuration-interaction approach for open quantum systems, the Gamow shell model, which provides a unitary description of quantum many-body system in different regimes of binding, and enables the unification in the description of nuclear structure and reactions. The Gamow shell model extends and generalizes the phenomenologically successful nuclear shell model to the domain of weakly-bound near-threshold states and resonances, offering a systematic tool to understand and categorize data on nuclear spectra, moments, collective excitations, particle and electromagnetic decays, clustering, elastic and inelastic scattering cross sections, and radiative capture cross sections of interest to astrophysics. The approach is of interest beyond nuclear physics and based on general properties of quasi-stationary solutions of the Schrödinger equation – so-called Gamow states. For the benefit of graduate students and newcomers to the field, the quantum-mechanical fundamentals are introduced in some detail. The text also provides a historical overview of how the field has evolved from the early days of the nuclear shell model to recent experimental developments, in both nuclear physics and related fields, supporting the unified description. The text contains many worked examples and several numerical codes are introduced to allow the reader to test different aspects of the continuum shell model discussed in the book.
A detailed review of the key models of nuclear structure and dynamics.
In the present volume, Phillip J. Siemens, who has been a seminal contributor to our understanding of the nucleus as a many-body system, and his able collabourator, Aksel S. Jensen, introduce graduate students and colleagues in other fields to the basic concepts of nuclear physics in a way which connects clearly the methods of nuclear physics with those of condensed matter, atomic, and particle physics. Their book thus provides a lucid introduction to the key facts and concepts of nuclei, including many of the most recent developments, while emphasizing the similarities and the differences between the behaviour of nuclei, atoms, elementary particles, and condensed matter, It should thus prove useful, not only as a text for an introductory graduate course in nuclear physics, but as a reference book for all scientists interested in a unified picture of our understanding of physical phenomena associated with many-body systems.
The idea of this symposium grew out of our discussions on the need to review the advances that had been made in the theoretical description of inelastic scattering reactions in the last few years. Since a microscopic description of inelastic scattering uses realistic effective interactions, we felt that it was appropriate to begin such a summary with a discussion of the free two-nucleon force. However as we thought further about this review, it became increasingly apparent that a rather more ambitious program linking the free two-nucleon force and nuclear matter calculations both to shell model calculations and to reaction theory, would be appropriate and perhaps even necessary to do full justice to the subject. We hope that the symposium as it emerged did fulfill these aims, better perhaps than we expected. There are some comments required concerning the presentation of the material. First the papers are grouped by session number for convenient gathering of the same topic in the same place. Secondly, because of the rather tight constraint on pages, it was possible to print only those contributions which were presented orally at the symposium. The remainner are included as abstracts. The full text of all the contributed papers is available as a Michigan State University Cyclotron Laboratory Report (MSUCL 39/1971).
