Book excerpt: These lectures concentrate on macroscopic aspects of nuclear dynamics, those aspects that come into prominence when the number of nucleons, A, is large, A” 1. An attempt is made to set up a theory of the dynamics of nuclear shape changes, for small (sub-sonic) collective velocities. To set up the equations of motion one needs three forces: conservative, dissipative, and inertial. The first lecture deals with statics, i.e., it discusses methods of treating the Potential Energy Function of nuclear systems. From the Potential Energy the conservative forces that drive the time evolution of a nuclear configuration can be deduced. The division of the underlying potential energy into Local, Proximity, and Global terms is stressed. The second lecture deals with dynamical aspects, especially with the nuclear Dissipation Function, which describes how dissipative frictional forces oppose the conservative driving forces. The underlying physics is the approximate validity of the Independent-Particle model. This, combined with the Randomization Hypothesis, leads to simple formulas that suggest that dissipative forces may often overshadow the inertial forces. The third lecture outlines the kind of dynamics that results from the balance of these forces, and describes a number of applications to nuclear fission and heavy-ion collisions of this New Dynamics. Particularly simple equations of motion are set up, and some of the consequences are explored. 18 references, 31 figures, 3 tables. (RWR).

Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade one of the most active areas of research in nuclear physics has been the study of systems of nucleons in various dynamical situations. Heavy-ion collisions at beam energies in the range 30-150 MeV per nucleon, where subnucleaonic degrees of freedom can be considered as frozen, allow such systems to be studied in detail. Nuclear

Available in PDF, EPUB and Kindle. Book excerpt: The 1985 Summer School on Nuclear Dynamics, organized by the Nuclear Physics Division of the Netherlands' Physical Society, was the sixth in a series that started in 1963. This year's topic has been nuclear dynamics rather than nuclear structure as in the foregoing years. This change reflects a shift in focus to nuclear processes at higher energy, or, more generally, to nuclear processes under less traditional circumstances. For many years nuclear physics has been restricted to the domain of the ground state and excited states of low energy. The boundaries between nuclear physics and high-energy physics are rapidly disappearing, however, and the future will presumably show that the two fields of research will contribute to one another. With the advent of a new generation of heavy-ion and electron accelerators research activities on various new aspects of nuclear dynamics over a wide range of energies have become possible. This research focuses in particular on nonnucleonic degrees of freedom and on nuclear matter under extreme conditions, which require the explicit introduction of quarks into the description of nuclear reactions. Mean-field formulations are no longer adequate for the description of nucleus nucleus collisions at high nucleon energies as the nucleon-nucleon collisions begin to dominate. Novel dynamical theories are being developed, such as those based upon the Boltzmann equation or hadrodynamic models. The vitality of nuclear physics was clearly demonstrated by the enthusiastic lecturers at this summer school. They presented a series of clear and thorough courses on the subjects above.

Available in PDF, EPUB and Kindle. Book excerpt: The 1988 Summer School on New Aspects of Nuclear Dynamics took place in the style that by now has become a tradition: a series of lectures by well known scientists on modem topics of nuclear physics, where special emphasis is placed on the didactic aspects of the lectures. In the past few years, we have witnessed a rapid evolution of the field of nuclear physics towards novel directions of research. This development is accompanied by the construction of some of the largest experimental facilities ever built for nuclear research. The subjects covered by the Summer School focussed on two main issues currently under active investigation and which will be pursued with the new facilities: the transition from nucleonic to quark degrees of freedom in the decription of nuclear reactions, and the behavior of nuclear matter as one approaches extreme densities and temperatures. These topics in many respects go beyond traditional nuclear physics and the speakers therefore also included high energy physicists. From the response of the participants it was clear that the program of the school filled a gap in the curriculum of many students. We wish to thank all the speakers for their well organized lectures, which were nicely geared to the level of the school, and for spending extra time on problem sessions and extensive discussions. The organization of this Summer School was made possible by substantial support from the Science Committee of the North Atlantic Treaty Organization.

Available in PDF, EPUB and Kindle. Book excerpt: Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.

Book excerpt: A qualitative classification of nucleus-nucleus reactions into four types is described, a consequence of the existence of up to three milestone configurations that a fusing system may be faced with. These considerations lead to phenomenological formulae for fusion and compound-nucleus cross-sections that may be compared with experiments by the use of rectilinear cross section plots. Examples of more specific model calculations of nuclear reactions employing the Chaotic Regime Dynamics are described. Some misunderstandings regarding the Wall and Wall-and-Window formulae, underlying this type of dynamics, are discussed in the appendix. 23 references.

Available in PDF, EPUB and Kindle. Book excerpt: th The 13 Winter Workshop on Nuclear Dynamics is the latest installment in a series of workshops that was started in 1978. This series has grown into a tradition, bringing together experimental and theoretical expertise from all areas of the study of nuclear dynamics. As always, the organizers had placed emphasis on the important aspect of cross fertilization between the different energy regimes and wa.ys of viewing a collision of energetic nuclei. This emphasis is reflected in the broad range of topics covered in these proceedings. Phase transitions in nuclear collisions received most of the attention during this workshop, as indicated by the number of contributions on this subject. Many of the questions in connection with these topics remain not settled and will have a huge impact on the physics that can be extracted from experiments at the future Relativistic Heavy Ion Collider. While the experimental program at the AGS is winding down, the NSCL upgrade and RHIC promise a bright future for our field in the USA. In Europe and Asia, major new facilities are under construction as well. The excitement and anticipation in connection with these new opportunities are reflected in these proceedings as well.

Download or read book Geometrical Relationships of Macroscopic Nuclear Physics written by Rainer W. Hasse and published by Springer. This book was released on 2012-01-06 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to provide a single reference source for the wealth of geometrical formulae and relationships that have proven useful in the descrip tion of atomic nuclei and nuclear processes. While many of the sections may be useful to students and instructors it is not a text book but rather a reference book for experimentalists and theoreticians working in this field. In addition the authors have avoided critical assessment of the material presented except, of course, by variations in emphasis. The whole field of macroscopic (or Liquid Drop Model) nuclear physics has its origins in such early works as [Weizsacker 35] and [Bohr 39]. It continued to grow because of its success in explaining collective nuclear excitations [Bohr 52] and fission (see the series of papers culminating in [Cohen 62]). These develop ments correspond to the first maximum in the histogram below, showing the distribution by year of the articles cited in our Bibliography. After the Liquid Drop Model had been worked out in some detail the development of the Struti nsky approach [Strutinsky 68] (which associates single particle contributions to the binding energy with the shape of the nucleus) gave new life to the field. The growth of interest in heavy-ion reaction studies has also contributed.
Download or read book Chiral Nuclear Dynamics written by Maciej A Nowak and published by World Scientific. This book was released on 1996-09-03 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physics of strongly interacting many-body systems known as nuclear physics is a mature discipline which has achieved a remarkably quantitative success. It has explained with an impressive accuracy the properties of nuclei from the deuteron to heavy nuclei containing several hundreds of nucleons. This is the more remarkable when one realizes that in no way did the success depend on the existence of, or knowledge derived from, the fundamental theory of strong interactions now believed to be quantum chromodynamics (QCD).This monograph is a first, albeit embryonic, attempt to explain how a nucleus can be understood without invoking the explicit degrees of freedom of quarks and gluons while still staying within the basic premise of QCD and furthermore why do quark-gluon signatures not show up prominently in nuclear processes, including those processes involving short-distance encounters within nuclei. Such an understanding is largely based on the modern concepts of broken chiral symmetry and is believed to be essential in uncovering new physics expected to figure in the hadronic environment under extreme conditions of high temperature and/or high density.

Available in PDF, EPUB and Kindle. Book excerpt: th This workshop was the 15 in a series that addresses the subject of the dynamics of nuclear reactions. These workshops are dedicated to the concept that bringing together scientists from diverse areas of nuclear reactions promotes the vibrant exchange of ideas. This workshop hosted presentations from experimentalists and theorists, intermediate energy to ultrarelativistic energies, and final results to recent speculations. Many of these scientists would not normally be exposed to the work done in other subfields. Thus the Winter Workshop on Nuclear Dynamics plays a unique role in information exchange and the stimulation of new ides. The field of nuclear dynamics has a bright future. New accelerators are being planned and completed around the world. New detectors are being constructed. New models and theories are being developed to describe these phenomena. The Winter Workshop on Nuclear Dynamics will continue to promote this lively and compelling field of research. WOLFGANG BAUER AND GARY D.
