Nuclear Reactions For Astrophysical Interest

Describes how the processes in stars which produce the chemical elements for planets and life may be reproduced in laboratories.

The Compound-Nuclear Reaction and Related Topics (CNR*) international workshop series was initiated in 2007 with a meeting near Yosemite National Park. It has since been held in Bordeaux (2009), Prague (2011), Sao Paulo (2013), Tokyo (2015), and Berkeley, California (2018). The workshop series brings together experts in nuclear theory, experiment, data evaluations, and applications, and fosters interactions among these groups. Topics of interest include: nuclear reaction mechanisms, optical model, direct reactions and the compound nucleus, pre-equilibrium reactions, fusion and fission, cross section measurements (direct and indirect methods), Hauser-Feshbach theory (limits and extensions), compound-nuclear decays, particle and gamma emission, level densities, strength functions, nuclear structure for compound-nuclear reactions, nuclear energy, nuclear astrophysics, and other topics. This peer-reviewed proceedings volume presents papers and poster summaries from the 6th International Workshop on Compound-Nuclear Reactions and Related Topics CNR*18, held on September 24-28, 2018, at Lawrence Berkeley National Lab, Berkeley, CA.

An Introduction to Experimental Nuclear Reactions is a book with a concise and simple approach to the subject of experimental nuclear physics. The subject being very technical, it is dealt with in a lucid way so that the reader can grasp the concept and later gain hands-on experience while doing fieldwork. In this book, theoretical, experimental and instrumentation aspects are covered with an emphasis on accelerator-based techniques, which form the basis for the subject of experimental nuclear physics. Other books on similar topics either concentrate on the physics aspects or are more focussed on the instrumentation and radiation detection techniques while accelerator-related concepts are less explained. One of the main standalone features of the book is its to-the-point approach so that the beginner is not lost in the never-ending details. This book discusses the following aspects: Basic introduction to nuclear reactions Two- and three-body kinematics Accelerator-based experimental techniques Basic aspects of the accelerator and accessories Vacuum physics Radiation detector physics and its associated electronics Theoretical modelling and errors This book is mainly intended for students who aspire to pursue a career in experimental nuclear physics research or work in a nuclear accelerator laboratory. Chinmay Basu, PhD, is a researcher in the field of experimental nuclear physics, and his present interests are in the field of low-energy nuclear astrophysics. He is a professor and head of an accelerator facility at the Saha Institute of Nuclear Physics, Kolkata, India.

Most elements are synthesized, or "cooked", by thermonuclear reactions in stars. The newly formed elements are released into the interstellar medium during a star's lifetime, and are subsequently incorporated into a new generation of stars, into the planets that form around the stars, and into the life forms that originate on the planets. Moreover, the energy we depend on for life originates from nuclear reactions that occur at the center of the Sun. Synthesis of the elements and nuclear energy production in stars are the topics of nuclear astrophysics, which is the subject of this book. It presents nuclear structure and reactions, thermonuclear reaction rates, experimental nuclear methods, and nucleosynthesis in detail. These topics are discussed in a coherent way, enabling the reader to grasp their interconnections intuitively. The book serves both as a textbook for advanced undergraduate and graduate students, with worked examples and end-of-chapter excercises, but also as a reference book for use by researchers working in the field of nuclear astrophysics.

A broad range of topics of current interest are discussed, from nuclear structure at the edge of stability to nuclear astrophysics and cosmic ray physics at the highest energies. Both the state of the art and basic background information are presented with a particular emphasis on interrelated research interests. The writers are all active scientists who enjoy the highest international reputation. They cover a range of problems of nuclear structure, in particular those concerning exotic nuclei and their decay modes, their relevance to nuclear reaction chains in stellar burning processes at various astrophysical sites, and as yet unsolved questions concerning the origin, acceleration mechanism, energy spectrum and elemental composition of high energy cosmic rays. Readership: Postgraduate physicists interested in the development of modern radioactive beam facilities, large array gamma ray and cosmic ray detectors, and new theoretical tools.

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

These peer-reviewed NIC XV conference proceedings present the latest major advances in nuclear physics, astrophysics, astronomy, cosmochemistry and neutrino physics, which provide the necessary framework for a microscopic understanding of astrophysical processes. The book also discusses future directions and perspectives in the various fields of nuclear astrophysics research. In addition, it also includes a limited number of section of more general interest on double beta decay and dark matter.
