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.

Available in PDF, EPUB and Kindle. Book excerpt: These proceedings contain selected topics covering various fields of collective motion and nuclear dynamics, ranging from low to high energies, from nuclear structure to reaction mechanisms, from regular stable to chaotic systems, and from fragmentation to fusion. Several ways of investigating the nuclear systems are presented: electron scattering radioactive beams, fragmenting projectiles, beta and double beta decays, and cluster emission. Their behaviour, under some extreme situations such as superdeformation, high spin states, high temperature, and relativisitic energy, is described within various theoretical formalisms.

Available in PDF, EPUB and Kindle. Book excerpt: The RIKEN Symposium was held in December of 1989 with 3 main goals in mind. The first goal was to survey the present status of studies in nuclear collective motion and nuclear reaction dynamics. The second goal was to look into future directions of the two topics. The third goal of the Symposium was to commemorate the work of the late Professor Taro Tamura.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Band Structure and Nuclear Dynamics contains a compilation of papers that were presented at the International Conference on Band Structure and Nuclear Dynamics. This volume examines the relationships between phenomenological models, such as the VMI, IBA and Bohr-Mottelson models, and it discusses the attempts to provide microscopic foundations for these models. It also reviews other boson expansion techniques. The book includes the experiments on rotating nuclei, which indicate that different phases, shapes, and angular momentum coupling schemes are suitable for different spin regions and different bands; and the HFB-cranking model, which provides a theoretical framework for the interpretation of these rotational phenomena. This volume is subdivided into six parts. The first part focuses on phenomenological collective models, including the theory of nuclear collective motion, VMI and other related models, and the boson-fermion model. Part two discusses strongly deformed nuclei, including the band structure and the structure of the collective bands in it from a microscopic point of view. This part also presents the Hartree-Fock-Bogoliubov theory and the application of the cranking model to Yb bands and band crossings. The third part focuses on transitional nuclei and covers IBA models, symmetric rotor interpretation of interpretation of transitional nuclei, electromagnetic properties of excited bands, and boson models. Part four describes the very high spin states and its Nilsson-Strutinsky model and self-consistent theory. Part five includes three special topics and Part six concludes by providing topics for a round-table discussion.

Available in PDF, EPUB and Kindle. Book excerpt: The collective effects in connection with certain systematic deviations of nuclear properties from the single particle estimate, in particular the giant quadrupole moments, are of a more subtle type than those considered by N. Bohr and Wheeler, and are intimately connected with the independent particle aspects of nuclear structure. In the past few years, these collective effects, as for example, those associated with the giant dipole state, can be incorporated into the shell model itself in terms of an interaction between pairs of shell model particles. The advantage of such a treatment is that it makes it possible to compute, in some detail, quantitative consequences of the interplay between the collective and single particle aspects of nuclear structure.
