Book Description
The workshop focused on theoretical descriptions of the nuclear reactions that can be studied at present and future radioactive beam facilities, from low to relativistic energies. These facilities allow for the study of reactions with exotic nuclei that have never been accessible before, providing challenges for reaction theory as well as important input for nuclear astrophysics. Overview of the standard reaction formalisms was an important component of the meeting, keeping in mind the old issues that arose from reactions with stable nuclei which help us understand the challenges of applying existing approaches to radioactive beams.

Book Description
Rare Isotope Beams (RIBs) are ion beams of exotic radioactive nuclei. The study of these nuclei is key to understanding the limits of nuclear existence, nucleo-synthesis in such violent stellar sites as supernovae and merging neutron stars, and the fundamental symmetries of nature. These nuclei also provide a unique probe to study condensed matter and many of them are potentially new radioisotopes for more effective medical diagnostics and therapy. Rare Isotope Beams: Concepts and Techniques gives an up-to-date overview of all these aspects of RIB science in a single volume containing the scientific motivation, production techniques, experimental techniques for studying exotic nuclei, methods used in condensed matter research, and medical applications. The emphasis throughout is on concepts to facilitate understanding of the essence of each topic in this diverse and cross-disciplinary field involving nuclear physics, astrophysics, and particle accelerators. A brief description of major RIB facilities is also presented. Exotic nuclei are difficult to produce in enough numbers and their production involves different nuclear reaction routes and a wide range of advanced technologies, which are presented in a comprehensive manner. Experimental techniques used to study exotic nuclei are provided with examples highlighting the intricate nature of such experiments. Another unique feature is the open-ended nature of the discussions, bringing out the future challenges and possibilities in this evolving field. The book offers an excellent overview of concepts and techniques involved in RIB science for new researchers entering the field as well as professionals.

Book Description
Discovering unexplored high-spin states in neutron-rich nuclei can open up a new direction to study band structure and the associated shell structure in isospin-asymmetric many-body systems. However, experimental reach has so far been limited to neutron-deficient or stable nuclei which are preferentially produced in fusion reactions used in such studies. By using neutron-rich rare-isotope beams, this limitation can be effectively removed, exposing previously inaccessible nuclei to this proven approach.This dissertation reports an experiment designed to kick off a spectroscopy program to study nuclear structure by means of low-energy nuclear reactions with reaccelerated rare-isotope beams available from the ReA3 facility at National Superconducting Cyclotron Laboratory. A 40Ar stable beam and a 45K rare-isotope beam impinged on a self-supporting lithium target to produce products ranging from argon to titanium via both direct and compound nucleus reactions. These mechanisms provide complementary tools to study the single-particle and collective natures of the states being probed. Using particle and gamma-ray coincidence relations between a silicon charged-particle detector and the Segmented Germanium Array, reaction channels were distinguished, and new properties were revealed, including for the nuclei 46Ca and 47K. For 46Ca, three new higher-lying states around 6 MeV and five new gamma-ray transitions were identified, suggesting three independent band structures formed from different particle-hole configurations. The rotational-like band built on the 0+2 state is established up to the tentatively assigned 6+2 state. New results are compared to large-scale shell model calculations, confirming the validity of the effective interaction describing particle-hole excitations across the Z=20 and N=28 shell gaps in the vicinity of doubly-magic 48Ca. Shape coexistence observed in lighter-mass calcium isotopes is suggested to persist in 46Ca, albeit as part of a transition from neutron to proton cross-shell excitations. For 47K, differential cross sections were extracted for the two-neutron transfer channel related to the present intruder configuration. Comparisons to Coupled Reaction Channels calculations indicate strong single-particle character for the states and a direct one-step process for the reaction itself. This work successfully developed the experimental techniques to use reaccelerated beams for spectroscopy of hitherto unexplored nuclei and demonstrated the ability of this approach to expand the experimental reach of nuclear structure studies.

Book Description
This book presents contributions from the Workshop on Rare Isotopes and Fundamental Symmetries, which was held on September 19-22, 2007, at the Institute for Nuclear Theory at the University of Washington. The book is the fourth in a series dedicated to exploring the science important to the proposed Facility for Rare Isotope Beams (FRIB). The topics covered by the contributions include Fermi beta decay, electron-neutrino correlations in nuclear beta decay: precision mass measurements, atomic parity violation, electric dipole moments, and hadronic parity violation and anapole moments.These topics highlight the recent work on the use of nuclei to understand the fundamental symmetries of nature. It presents current results as well as proposals for future experiments.

Book Description
Over ten years ago, U.S. nuclear scientists proposed construction of a new rare isotope accelerator in the United States, which would enable experiments to elucidate the important questions in nuclear physics. To help assess this proposal, DOE and NSF asked the NRC to define the science agenda for a next-generation U.S. Facility for Rare Isotope Beams (FRIB). As the study began, DOE announced a substantial reduction in the scope of this facility and put off its initial operation date by several years. The study focused on an evaluation of the science that could be accomplished on a facility reduced in scope. This report provides a discussion of the key science drivers for a FRIB, an assessment of existing domestic and international rare isotope beams, an assessment of the current U.S. position about the FRIB, and a set of findings and conclusions about the scientific and policy context for such a facility.
