This book introduces the reader to the field of nuclear astrophysics, i.e. the acquisition and reading of measurements on unstable isotopes in different parts of the universe. The authors explain the role of radioactivities in astrophysics, discuss specific sources of cosmic isotopes and in which special regions they can be observed. More specifically, the authors address stars of different types, stellar explosions which terminate stellar evolutions, and other explosions triggered by mass transfers and instabilities in binary stars. They also address nuclear reactions and transport processes in interstellar space, in the contexts of cosmic rays and of chemical evolution. A special chapter is dedicated to the solar system which even provides material samples. The book also contains a description of key tools which astrophysicists employ in those particular studies and a glossary of key terms in astronomy with radioactivities.
The Second International Conference on Fission and Properties of Neutron-Rich Nuclei continued the emphasis on fission models, fission processes, properties of neutron-rich nuclei and new directions. The responses to the conference were so extensive that 44 talks were presented in individual sessions and 35 more in two afternoons of parallel sessions. New insights and developments were discussed, including experimental and theoretical studies of ternary fission with correlated pairs with emission of a third nucleus such as helium-3, alpha particle, and beryllium-10; the structure of neutron-rich nuclei from spontaneous fission, heavy-ion-induced fission and knock-out reactions; comparisons of deep inelastic reactions and fission for production of neutron-rich nuclei; production of superheavy elements, including the discovery of element 114; experiments with radioactive beams; and proposals for new radioactive ion beam facilities.
Dealing with astrophysics derived from the radiation emitted by radioactive atomic nuclei, this book describes the different methods used to measure cosmic radio-isotopes. It demonstrates how this astronomical window has contributed to the understanding of the sources and the chemical evolution of cosmic gas. Reference materials and explanations are included for students in advanced stages of their education. Nuclear reactions in different sites across the universe lead to the production of stable and unstable nuclei. Their abundances can be measured through different methods, allowing to study the various nuclear processes taking place in cosmic environments. Nucleosynthesis is the cosmic formation of new nuclear species, starting from hydrogen and helium resulting from the big bang origins. Stars create and eject synthesized nuclei during their evolution and explosions. Incorporation of the new interstellar composition into next-generation stars characterises the compositional (chemical) evolution of cosmic gas in and between galaxies. Radioactive species have unique messages about how this occurs. Since the first Edition of this book published in 2011 with the title Astronomy with Radioactivities, long-awaited new direct observations of supernova radioactivity have been made and are now addressed in two updated chapters dealing with supernovae. In this second Edition, the advances of recent years beyond one-dimensional treatments of stellar structure and stellar explosions towards 3-dimensional models have been included, and led to significant re-writings in Chapters 3-5. The sections on the Solar System origins have been re-written to account for new insights into the evolution of giant molecular clouds. The chapter on diffuse radioactivities now also includes material measurements of radioactivities in the current solar system, and their interpretations for recent nucleosynthesis activity in our Galaxy. Significant new results on gamma-rays from positron annihilations have been accounted for in that chapter, and led to new links with nucleosynthesis sources as well as interstellar transport processes. A new chapter now provides a description of interstellar processes often called 'chemical evolution', thus linking the creation of new nuclei to their abundance observations in gas and stars. The experimental / instrumental chapters on nuclear reaction measurements, on gamma-ray telescopes, and pre-solar grain laboratories have been updated. Moreover, new windows of astronomy that have been opened up in recent years have been included in the discussions of the multi-messenger approach that broadens the basis for astrophysical insights.
The Sixth Latin American Symposium on Nuclear Applications covered the most active topics in basic nuclear physics which were grouped into four broad categories, namely, nuclear structure, nuclear reactions, subnuclear physics, and nuclear thermodynamics and dynamics. It also placed a significant emphasis on the applications of nuclear science and nuclear instrumentation to a wide range of fields of knowledge.
The papers in this proceedings volume describe the research and applications of low energy accelerators. The research is primarily in the field of nuclear and atomic physics. The applications are: ion implantation and all of the ion beam diagnostic techniques that are currently in use with small accelerators.
All papers have been peer-reviewed. This book contains the lectures given at the joint meeting “Ninth Torino Workshop on Evolution and Nucleosynthesis in AGB Stars” and “Second Perugia Workshop in Nuclear Astrophysics”, held together in Perugia (Italy) from October 21 to October 26, 2007. In the present book, the fields covered by the lecturers are quite wide: the joining of the “Torino Workshops” strictly focused on AGB stars, and of the “Perugia Workshops” dedicated to a broader view of Nuclear Astrophysics, resulted in a coordinated, but widely interdisciplinary discussion, where AGB nucleosynthesis could be integrated by complementary issues concerning nuclear processes in massive stars, while the observational sessions usually dominated by spectroscopic results on stellar atmospheres and laboratory measurements on solar and pre-solar system materials could be complemented by the rich information now coming from space-borne infrared photometry.
All papers were peer reviewed. This conference focused on the broad field of nuclear data, their production, dissemination, and testing, with the goal of providing reliable data for applications such a nuclear fission and fusion energy, accelerators, spallation neutron sources, nuclear medicine, environment, space, non-proliferation, nuclear safety, astrophysics and cosmology, and basic research.
