Available in PDF, EPUB and Kindle. Book excerpt: Nuclear reactions at energies near and below the Coulomb barrier have found much interest since unexpectedly large cross sections of fusion for heavy ions were discovered around 1980. This book covers the more important experimental and theoretical aspects such as sub-barrier fusion, sub- and near-barrier transfer, couplings of various reaction channels, neck-formation, the threshold anomaly, spin distributions and fusion of polarized ions. The symposium also included a session devoted to mass spectrometry for fast reaction products.

Book excerpt: Fusion reactions between different Kr and Ni isotopes were measured recently at ATLAS. We performed coupled-channels calculations and made comparisons to the measurements. Such calculations become increasingly difficult for heavy, soft nuclei due to strong couplings and the importance of higher-order, multi-step processes. The calculations were made possible by adopting the so-called rotating frame approximation, and they included one- and two-phonon excitations of the low-lying 2 and 3− states in both the projectile and the target. These calculations reproduced quite accurately the measured fusion cross sections for a beam of 86Kr. Some discrepancies remain for the much softer 78Kr nucleus; the calculations were clearly much more sensitive to higher-order processes in this case. In particular, it was important to implement the correct coupling strength and excitation energy for the soft, one- to two-phonon quadrupole transition in 78Kr, which differs significantly from the vibrational limit. This work was performed in collaboration with the experimentalists and was submitted for publication.

Available in PDF, EPUB and Kindle. Book excerpt: The title covers a very broad area of both experimental and theoretical studies. The common characteristic of heavy-ion collisions at these energies, compared to what is usually seen at higher energies, is the important interplay between different reaction channels or internal degrees of freedom. The couplings between the various channels can result in important multistep contributions to a given channel. These often have to be treated explicitly, for example by solving the appropriate set of coupled equations. In contrast, at higher energies the effects of these couplings frequently can be represented in a simple, average way, as is done when one introduces an imaginary part to the optical potential for elastic scattering. At first, it might be thought that the possible importance of multistep transitions would be a strong disadvantage of working at these energies. However, although the analysis of the data becomes more complicate, the study of these terms and their interferences can be a rich source of information. In particular, it can tell us, indirectly, something about transitions between two excited states. Overviews of some of these phenomena have been presented elsewhere; here I have selected two topics as representative. Even then I cannot go into much detail, so perhaps this paper is best regarded as providing some references as the stating point for a literature search.
Download or read book Heavy Ion Reactions written by Ricardo A. Broglia and published by CRC Press. This book was released on 2018-03-09 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining elastic and inelastic processes with transfer reactions, this two-part volume explores how these events affect heavy ion collisions. Special attention is given to processes involving the transfer of two nucleons, which are specific for probing pairing correlations in nuclei. This novel treatment provides, together with the description of surface vibration and rotations, a unified picture of heavy ion reactions in terms of the elementary modes of nuclear excitation. Heavy Ion Reactions is essential reading for beginning graduate students as well as experienced researchers.

This book was released on 1993-11-01 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume discusses primarily the characteristics of reactions induced by unstable nuclei and aims to guide future directions in this area of research. In addition, the present status of research in related fields is reviewed. The topics discussed can be broadly classified into: fusion and transfer reactions with stable nuclei, fission and molecular resonance, structure of unstable nuclei, reactions with unstable nuclei, synthesis of superheavy elements and heavy-ion fusion with neutron-rich beams.

Book excerpt: All papers have been peer-reviewed. The fusion of two nuclei is an important process for producing nuclei that do not exist on Earth. This conference discussed aspects of the reaction mechanism leading to fusion as well as nuclear structure aspects of unstable nuclei produced via fusion reactions. The main emphasis was on low (Coulomb barrier) energies.

Download or read book Heavy Ion Reactions at Low Energies written by Valery Zagrebaev and published by Springer Nature. This book was released on 2019-11-20 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on Valery Zagrebaev's original papers and lecture materials on nuclear physics with heavy ions, which he prepared and extended through many years for the students of nuclear physics specialties. Thе book outlines the main experimental facts on nuclear reactions involving heavy ions at low energies. It focuses on discussions of nuclear physics processes that are a subject of active, modern research and it gives illustrative explanations of these phenomena in the framework of up-to-date theoretical concepts. This textbook is intended for students in physics who have completed a standard course of quantum mechanics and have basic ideas of nuclear physics processes. It is designed as a kind of lifeboat that, at the end of the course, will allow students to navigate the modern scientific literature and to understand the goals and objectives of current, on-going research.
Download or read book Theoretical Approaches of Heavy Ion Reaction Mechanisms written by M. Martinot and published by Elsevier. This book was released on 2016-06-03 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical Approaches of Heavy Ion Reaction Mechanisms provides information pertinent to heavy ion reactions and nuclear fission at low energies. This book discusses the features of the time-dependent solution of the Kramer–Chandrasekhar equation. Organized into 27 chapters, this book begins with an overview of the deexcitation process of a highly excited nucleus by means of its decay into two fragments. This text then presents a microscopic description to extract the characteristics features of the collective dynamics of the fission process at low energy. Other chapters consider nuclear fission as a transport process over the fission barrier. This book discusses as well the microscopic foundations of the phenomenological collective models. The final chapter deals with the composition of the baryons and mesons in terms of gluons and quarks. This book is a valuable resource for nuclear and high energy physicists. Experimentalists, theoreticians, and research workers will also find this book useful.
