Book Description
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.

Book Description
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 Description
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.

Book Description
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.

Book Description
The ?eld of nuclear physics is entering the 21st century in an interesting and exciting way. On the one hand, it is changing qualitatively since new experim- tal developments allow us to direct radioactive and other exotic probes to target nuclei as well as to sparko? extremely energetic nuclear collisions. In parallel, detector systems are of an impressive sophistication. It is di?cult to envisage all the discoveries that will be made in the near future. On the other hand, the app- cations of nuclear science and technology are broadening the limits in medicine, industry, art, archaeology, and the environmental sciences, etc. This implies that the public perception of our ?eld is changing, smoothly but drastically, in c- trast to former times where nuclear weapons and nuclear power plants were the dominant applications perceived by citizens. Both aspects, scienti?c dynamism and popular recognition, should lead the ?eld to an unexpected revival. One of the consequences of the former could be that many brilliant students consider nuclear physics as an excellent ?eld in which to acquire professional expertise. Therefore, one of the challenges of the international nuclear physics community is to try to make the ?eld attractive. That means simply being pedagogic and enthusiastic. Thus, as organisers of an already established summer school, our contribution was to put an emphasis in this session on pedagogy and enthusiasm.

Book Description
'The field has expanded in so many directions, in connection with the increase in accessible energy, angular momentum, and nuclear species, and the new phenomena, which have been revealed, have stimulated conceptual developments concerning the significant degrees of freedom and their interplay in nuclear dynamics ... it would be impossible for us to provide an assessment of this vastly expanded subject with anything like the degree of comprehensiveness aimed at in the original text. At the same time, this text continues to describe the basis for the understanding of nuclear structures as we see it today ...'foreword from the new prefaceAfter many years, this classic two-volume treatise is now available again in an unabridged reprint. These volumes present the basic features of nuclear structure in terms of an integration of collective and independent particle aspects and remain a foundation for current efforts in the field. Central to the book's value is an approach that recognizes the many connections between concepts of nuclear physics and those of other many-body systems, and that deals boldly with the interplay between theory and experiment. Aside from the main text, which provides a systematic exposition of the subject, there are sections labeled ';Illustrative Examples';, which present detailed analyses of experimental results and the manner in which they illuminate the concepts developed in the text. Many useful appendices on general theoretical tools are also included, covering topics such as angular momentum algebra, symmetry problems, statistical description of level densities, and theory of nuclear reactions and decays.
