Book Description
The dissipative nuclear reaction mechanism in low energy light heavy-ion collisions have been studied. Inclusive energy distributions for various fragments and light charged particles have been measured in a wide angular range in several reactions. In the 20Ne+12C reaction, the fragment yield was mostly from the equilibrium decay of composite system, although the cross-sections for B, C, N fragments were higher than the statistical model predictions. This enhancement in cross-section indicated the survival of orbiting-like phenomenon at the energy > 7 MeV/nucleon. The composite system is also deformed. In 20Ne+27Al reaction, both deep-inelastic and fusion-fission processes were found to contribute significantly to the fragment yield. The time scale for the deep-inelastic process was 10-22 seconds. It has been found that the extracted values of angular momentum dissipation were more than the corresponding phenomenological (sticking) limit predictions for light fragments. In addition, in- plane coincidence data gives information about the decay of the hot composite formed 20Ne+12C reaction at 158 MeV.

Book Description
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.

Book Description
The relevance of studies of light-particle emission associated with damped nuclear reactions for investigating properties of the reaction mechanism, in particular of the energy dissipation mechanism, is discussed. Processes of instantaneous particle emission are reviewed, as related to heavy-ion reactions. Methods are outlined concerning information on the conditions of the intermediate nuclear system at scission revealed in the processes of statistical particle evaporation from the reaction fragments. They are employed in studies of neutron emission in the damped reactions 165Ho+56Fe and 165Ho+136Xe, yielding evidence for a rapid thermalization and a relaxation of the mass-to-charge asymmetry of the system. Progress is reported for attempts to achieve a unified description of energy dissipation, nucleon exchange, and particle emission in damped nuclear reactions. 19 figures, 1 table.
