Book Description
Recent developments in nuclear-structure calculations used to calculate the nuclear properties of neutron-rich heavy elements can have a dramatic effect on astrophysical r-process calculations. In particular, in the context of the macroscopic-microscopic method, studies of the effect of the finite range of the nuclear force on the surface energy, the shape dependence of the Wigner term, new shape degrees of freedom near scission, and improved single particle potentials for neutron-rich heavy elements have led to improved calculations of the properties of heavy elements. We will discuss preliminary applications of these new models to nuclei of interest in the astrophysical r-process and the implications for nuclear cosmochronology and the existence of superheavy elements in nature. 14 refs., 6 figs.

Book Description
Covers all the phenomenological and experimental data on nuclear physics and demonstrates the latest experimental developments that can be obtained. Introduces modern theories of fundamental processes, in particular the electroweak standard model, without using the sophisticated underlying quantum field theoretical tools. Incorporates all major present applications of nuclear physics at a level that is both understandable by a majority of physicists and scientists of many other fields, and usefull as a first introduction for students who intend to pursue in the domain.

Book Description
The proceedings of this conference should be of interest to nuclear physicists (researchers, university and college professors, graduate and post-graduate students). FINUSTAR 3 covered a wide spectrum of research activities in nuclear structure, nuclear astrophysics and nuclear reactions that due to common instrumentation and research facilities have been overlapping strongly over the last years. The topics in nuclear structure, astrophysics and reactions, experimental and theoretical, covered by FINUSTAR 3 are as follows: Nuclear structure at the extremes Collective phenomena and phase transitions in nuclei Exotic excitations Synthesis and structure of the heaviest elements Nuclear masses and ground state properties Ab-initio calculations and the shell model Mean field theories, cluster models and molecular dynamics Scattering and reaction dynamics at low and intermediate energies Nuclear reactions off stability and indirect methods Neutrinos in nuclear astrophysics and astro-particle physics Nuclear astrophysics (Big-Bang, s-, r- and p-process & nuclide production) Radioactive and exotic relativistic beams Facilities and instrumentation for the future

Book Description
Nuclear astrophysics as it stands today is a fascinating science. Even though, compared to other scientific fields, it is a young discipline which has developed only in this century, it has answered many questions concerning the under standing of our cosmos. One of these great achievements was the concept of nucleosynthesis, the creation of the elements in the early universe in interstellar matter and in stars. Nuclear astrophysics has continued, to solve many riddles of the evolution of the myriads of stars in our cosmos. This review volume attempts to provide an overview of the current status of nuclear astrophysics. Special emphasis is given to the interdisciplinary nature of the field: astronomy, nuclear physics, astrophysics and particle physics are equally involved. One basic effort of nuclear astrophysics is the collection of ob servational facts with astronomical methods. Laboratory studies of the nuclear processes involved in various astrophysical scenarios have provided fundamen tal information serving both as input for and test of astrophysical models. The theoretical understanding of nuclear reaction mechanisms is necessary, for example, to extrapolate the experimentally determined reaction rates to the thermonuclear energy range, which is relevant for the nuclear processes in our cosmos. Astrophysical models and calculations allow us to simulate how nuclear processes contribute to driving the evolution of stars, interstellar matter and the whole universe. Finally, elementary particle physics also plays an important role in the field of nuclear astrophysics, for instance through weak interaction processes involving neutrinos.

Book Description
Physicists have devoted much effort to reproducing the conditions of the primordial universe in laboratory conditions in their quest to work out a comprehensive theory of the appearance and evolution of nuclear matter. Whether it be trying to recreate the predicted primordial state of high-energy density matter in which quarks and gluons are effectively deconfined - the so-called Quark Gluon Plasma (QGP) - or exploring the structure and reaction properties of very unstable nuclei in experiments using radioactive beams, they have striven to understand the events which characterized the Big Bang and the various nucleosynthesis mechanisms which occur in the stars. This book contains the proceedings of the 2010 Enrico Fermi summer school held in Varenna, Italy, in July 2010, and devoted to the present understanding of the primordial universe and the origin of the elements, as achieved by studying nuclei and their constituents in extreme regimes of energy and composition. Subjects covered include: QGP formation; exotic nuclei, their degrees of freedom from the ground state and the properties of the excited states; the complex, but appealing theory describing the supernovae explosion and neutron stars; dark energy and matter; Big Bang nucleosynthesis and energy and solar neutrino production; nuclear cosmochronology; beta and gamma decay relevant for the nucleosynthesis of heavy nuclei. The annual Enrico Fermi summer school is internationally renowned and this book will be of great interest to all those involved in the field of nuclear physics.

Book Description
This textbook is a unique and ambitious primer of nuclear physics, which introduces recent theoretical and experimental progresses starting from basics in fundamental quantum mechanics. The highlight is to offer an overview of nuclear structure phenomena relevant to recent key findings such as unstable halo nuclei, superheavy elements, neutron stars, nucleosynthesis, the standard model, lattice quantum chromodynamics (LQCD), and chiral effective theory. An additional attraction is that general properties of nuclei are comprehensively explained from both the theoretical and experimental viewpoints. The book begins with the conceptual and mathematical basics of quantum mechanics, and goes into the main point of nuclear physics – nuclear structure, radioactive ion beam physics, and nuclear reactions. The last chapters devote interdisciplinary topics in association with astrophysics and particle physics. A number of illustrations and exercises with complete solutions are given. Each chapter is comprehensively written starting from fundamentals to gradually reach modern aspects of nuclear physics with the objective to provide an effective description of the cutting edge in the field.

Book Description
This book aims to provide a detailed introduction to the state-of-the-art covariant density functional theory, which follows the Lorentz invariance from the very beginning and is able to describe nuclear many-body quantum systems microscopically and self-consistently. Covariant density functional theory was introduced in nuclear physics in the 1970s and has since been developed and used to describe the diversity of nuclear properties and phenomena with great success.In order to provide an advanced and updated textbook of covariant density functional theory for graduate students and nuclear physics researchers, this book summarizes the enormous amount of material that has accumulated in the field of covariant density functional theory over the last few decades as well as the latest developments in this area. Moreover, the book contains enough details for readers to follow the formalism and theoretical results, and provides exhaustive references to explore the research literature.
