Download or read book Nuclear Collective Motion written by David J. Rowe and published by World Scientific. This book was released on 2010 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two most important developments in nuclear physics were the shell model and the collective model. The former gives the formal framework for a description of nuclei in terms of interacting neutrons and protons. The latter provides a very physical but phenomenological framework for interpreting the observed properties of nuclei. A third approach, based on variational and mean-field methods, brings these two perspectives together in terms of the so-called unified models. Together, these three approaches provide the foundations on which nuclear physics is based. They need to be understood by everyone practicing or teaching nuclear physics, and all those who wish to gain an understanding of the foundations of the models and their relationships to microscopic theory as given by recent developments in terms of dynamical symmetries. This book provides a simple presentation of the models and theory of nuclear collective structure, with an emphasis on the physical content and the ways they are used to interpret data. Part 1 presents the basic phenomenological collective vibrational and rotational models as introduced by Bohr and Mottelson and their many colleagues. It also describes the extensions of these models to parallel unified models in which neutrons and protons move in a mean-field with collective degrees of freedom. Part 2 presents the predominant theories used to describe the collective properties of nuclei in terms of interacting nucleons. These theories, which are shared with other many-body systems, are shown to emerge naturally from the unified models of Part 1.

Book excerpt: This report discusses three different subjects. The first is the development of a generalized version of the VMI (variable moment of inertia) model that ties it to the original form of the IBM (interacting boson model) and provides a possibility of fitting vibrational spectra with generalized vibrational formulas. The second is a suggestion for fitting band crossing calculations of the phenomenological type more completely than has hitherto been done into the framework of the VMI method. The third, which is the most important and far reaching, is the description f a complete mathematical method for the microscopic derivation of the IBM from a conventional shell-model Hamiltonian. In addition to elements already foreseen by previous authors, there is proposed a solution for the most important problem outstanding, not only within the framework of the IBM, but also in all previous work on boson expansion. This is the problem of actually selecting, in a general fashion, the most collective excitations. A criterion is introduced that the subspace constructed from these excitations should possess an average energy that is lower than the rest of the shell model space; the actual implementation of this criterion is explained. 8 tables, 62 references.

Book excerpt: Current developments in nuclear structure are discussed from a theoretical perspective. First, the progress in theoretical modeling of nuclei is reviewed. This is followed by the discussion of nuclear time scales, nuclear collective modes, and nuclear deformations. Some perspectives on nuclear structure research far from stability are given. Finally, interdisciplinary aspects of the nuclear many-body problem are outlined.

This book was released on 1997-07-01 with total page 762 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of the international meeting covered a broad range of the recent developments in nuclear physics, from heavy-ion collisions from Coulomb barrier through relativisitc energies (using stable and radioactive beams), to some applications of nuclear physics and other research fields. The lectures given at the meeting range from the most recent progress to future prospects in nuclear physics research.This volume focuses on recent developments in nuclear physics, with emphasis on the investigation of processes connected with large-amplitude collective motion in nuclei, such as heavy-ion fusion, giant multipole resonances, and nuclear fission and fragmentation.
Download or read book Nuclear Structure from a Simple Perspective written by R. Casten and published by . This book was released on 2000 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook on nuclear structure takes a unique approach to the topic, explaining nuclear structure by building on a few elementary physical ideas. Intricate topics such as shell model residual interactions, the Nilsson model, and the RPA analysis of collective vibrations are explained in a simple, intuitive way so that predictions can usually be made without calculations, essentially by inspection. Frequent data comparison shows the relevance of theoretical approaches. New to this edition are chapters on exotic nuclei and radioactive beams,and correlations of collective observables. Completely new discussions are given on isopin, the shell model, nature of collective vibrations, multi- phonon states, superdeformation, bandmixing, the geometric collective model, the fermei gas model, basic properties of simple nuclear potentials, the deuteron, etc.
