Book Description
A systematic study of reaction mechanisms at intermediate energies (50--100 MeV/A) has been performed at the Lawrence Berkeley Laboratory's BeValac using medium weight projectiles on medium and heavy element targets. A gas and plastic phoswich detector system was employed which gave large geometric coverage and a wide dynamic response. The particles identified with the gas detectors could be characterized into three components - intermediate mass fragments (IMF), fission fragments (FF) and heavy residues (HR). Major observed features are: the reaction yields are similar in the 50 to 100 MeV/A range, central collisions have high multiplicity of IMF's with broad angular correlations consistent with a large participant region, effects of final state Coulomb interactions are observed and give information on the size and temporal behavior of the source, true fission yields are dependent on target fissility and correlated with relatively peripheral collisions. Analysis of fission and evaporation yields implies limiting conditions for which fission decay remains a viable deexcitation channel. 7 figs.

Book Description
This book presents recent results on experimental and theoretical studies of the interaction of heavy ions with nuclei at low and intermediate energies: the dynamics of fusion and decay of complex nuclear systems, the synthesis of superheavy elements, the synthesis and properties of exotic nuclei close to the proton and neutron driplines, nuclear fission, nuclear structure, and reactions with stable and radioactive ion beams. It also covers some aspects of applied physics research: track membranes and their applications, the use of polymers in medicine and electronics, production and application of radioisotopes for medical purposes, and environmental protection.

Book Description
This book provides a collection of reviews of some of the recent developments in nuclear physics research at intermediate energies from across the globe. It especially focuses on the most essential aspects, such as multifragmentation and associated phenomena in nuclear collisions, with the incident energy region between a few MeV and several hundreds of MeV/nucleon. The topic of the book—multifragmentation—was chosen based on the fact that all heavy-ion collisions revolve around a fragmenting system, which is also thought to have a link to phase transitions. One unique and valuable dimension of this book is that it has brought together the research of several experts working in the field of intermediate energy heavy-ion collisions in various renowned laboratories of the world. It provides a thorough review of the recent developments in various related phenomena, especially multifragmentation, observed at the intermediate-energy range, both theoretically and experimentally. It extensively discusses the concept of nuclear symmetry energy, which is important for the nuclear physics and astrophysics communities. In addition, the book identifies potential research directions and technologies that will drive future innovations. It will serve as a valuable reference for a larger audience, including students who wish to pursue a career in nuclear physics and astrophysics.

Book Description
Results are presented on cross sections, parallel and perpendicular momentum transfers, charge loss and velocity systematics for fission following reactions of Fe and Nb projectiles at 50--100 MeV/A on targets of Ta, Au, and Th. The results at 100 MeV/A are compared to a detailed multistage deexcitation model. The initial collision is modeled with an intranuclear cascade. The resultant excited target residues then undergo a fast preequilibrium decay stage followed by a statistical decay involving nucleon evaporation and fission. Results from this modeling are in reasonable agreement with experimental data. 14 refs., 11 figs.

Book Description
This volume comprises select peer-reviewed papers from the Indo-French Workshop on Multifragmentation, Collective Flow, and Sub-Threshold Particle Production in Heavy-Ion Reactions held at the Department of Physics, Panjab University, Chandigarh, India in February, 2019. The contents highlight latest research trends in intermediate energy nuclear physics and emphasize on the various reaction mechanisms which take place in heavy-ion collisions. The chapters contribute to the understanding of interactions that govern the dynamics at sub-nucleonic level. The book includes contributions from global experts hailing from major research facilities of nuclear physics, and provides a good balance between experimental and theoretical model based studies. Given the range of topics covered, this book can be a useful reference for students and researchers interested in the field of heavy-ion reactions.
