This book was released on 2009 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years, much progress has been made towards the understanding of basic properties of nuclei with extreme neutron to proton ratios. However, the study of phenomena involving spin polarized nuclei near the drip lines remains practically unexplored. The importance of such studies lies in the fact that the most complete knowledge of the scattering matrix is obtained in reactions with polarized particles. The purpose of this dissertation was to explore the feasibility of using polarized probes in reactions with exotic nuclei. We identified areas where reactions between Radioactive Ion Beams (RIBs) and light polarized targets open a new window of opportunity to study the behavior of those nuclei. These include nuclear structure studies using elastic scattering, the investigation of isolated resonances in nuclei of interest for astrophysics, the study of weakly bound nuclei, one nucleon transfer reactions, and reaction mechanisms. Motivated by these potential applications, we developed a polarized proton target with unique capabilities to operate in reactions with heavy ions at low and intermediate energies. Protons in a plastic foil are polarized using the dynamic nuclear polarization method, which requires low temperature operation (~200 mK) and intense magnetic fields (2.5 T). The foils can be prepared using the spin coating technique, resulting in thicknesses between 100 [mu]g/cm2 and 20 mg/cm2. We have demonstrated operation of the target in frozen spin mode (low magnetic field, e.g., 0.8 T), required for experiments at low energies. For experiments with fast beams the target can be operated in dynamic mode reaching polarizations of up to 30% (B=2.5 T, continuous microwave irradiation). The operational limits of the target have been explored at the Paul Scherrer Institute and at the Holifield Radioactive Ion Beam Facility using the thick target technique with 12C beams at 38 MeV and intensities up to 107 pps, corresponding to the most intense RIBs available. The dissertation concludes with a series of recommendations for future improvements on the target systems and suggesting the use of the target to further investigate weakly bound systems.

This book was released on 2018-10-13 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of protons and neutrons, or "nucleons"â€"the building blocks of atomic nucleiâ€"has advanced dramatically, both theoretically and experimentally, in the past half century. A central goal of modern nuclear physics is to understand the structure of the proton and neutron directly from the dynamics of their quarks and gluons governed by the theory of their interactions, quantum chromodynamics (QCD), and how nuclear interactions between protons and neutrons emerge from these dynamics. With deeper understanding of the quark-gluon structure of matter, scientists are poised to reach a deeper picture of these building blocks, and atomic nuclei themselves, as collective many-body systems with new emergent behavior. The development of a U.S. domestic electron-ion collider (EIC) facility has the potential to answer questions that are central to completing an understanding of atoms and integral to the agenda of nuclear physics today. This study assesses the merits and significance of the science that could be addressed by an EIC, and its importance to nuclear physics in particular and to the physical sciences in general. It evaluates the significance of the science that would be enabled by the construction of an EIC, its benefits to U.S. leadership in nuclear physics, and the benefits to other fields of science of a U.S.-based EIC.

This book was released on 2006-07-24 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second volume in a series of lecture notes based on the highly s- cessful Euro Summer School on Exotic Beams that has been running yearly since 1993 (apart from 1999) and is planned to continue to do so. It is the aim of the School and these lecture notes to provide an introduction to - dioactive ion beam (RIB) physics at the level of graduate students and young postdocs starting out in the ?eld. Each volume will contain lectures covering a range of topics from nuclear theory to experiment to applications. Our understanding of atomic nuclei has undergone a major re-orientation over the past two decades and seen the emergence of an exciting ?eld of research: the study of exotic nuclei. The availability of energetic beams of short-lived nuclei, referred to as radioactive ion beams (RIBs), has opened the way to the study of the structure and dynamics of thousands of nuclear species never before observed in the laboratory. In its 2004 report “Persp- tives for Nuclear Physics Research in Europe in the Coming Decade and - yond”, the Nuclear Physics European Collaboration Committee (NuPECC) statesthatthe?eldofRIBphysicsisoneofthemostimportantdirectionsfor the future science programme in Europe. In 2005 it published its “Roadmap for Construction of Nuclear Physics Research Infrastructures in Europe”.
