Book Description
This book brings together various aspects of the nuclear fission phenomenon discovered by Hahn, Strassmann and Meitner almost 70 years ago. Beginning with an historical introduction the authors present various models to describe the fission process of hot nuclei as well as the spontaneous fission of cold nuclei and their isomers. The role of transport coefficients, like inertia and friction in fission dynamics is discussed. The effect of the nuclear shell structure on the fission probability and the mass and kinetic energy distributions of the fission fragments is presented. The fusion-fission process leading to the synthesis of new isotopes including super-heavy elements is described. The book will thus be useful for theoretical and experimental physicists, as well as for graduate and PhD students.

Structural Physics of Nuclear Fusion
Author: Stoyan Sarg
Publisher: Createspace Independent Pub
ISBN: 9781482620030
Category : Science
Languages : en
Pages : 212
Book Description
Remarkable advances in cold fusion experiments have raised the hope for a safer and cheaper nuclear energy. The results, however, cannot be explained from the point of view of current physical understanding of nuclear fusion. This is an obstacle to endorsement and investment in this field. The research needs a supporting theory. The present book suggests a new approach for analysis of the results and offers practical recommendations based on the physical models of atomic nuclei derived in the BSM-Supergravitation Unified theory (BSM-SG). The book provides: (1) a method for analysis of the LENR experiments using the BSM-SG atomic models; (b) a selection of isotopes suitable for a more efficient energy yield with a minimum of radioactive byproducts; (c) practical considerations for selection of the technical method and the reaction environment.The BSM-SG theory is based on a concept of space that follows the view of Michael Faraday and the recommendations of James Maxwell about the properties of the envisioned space medium, known as Aether. The concept of an Aether (Ether) was abandoned in favor of the quantum mechanical formalism adopted in the first quarter of 20th century. However, Albert Einstein was against this approach and openly expressed his concerns after he developed General Relativity. In his monograph “Sidelights on relativity” (1921) he wrote: “To deny the ether is ultimately to assume that empty space has no physical qualities whatever” (p.23) and “According to general theory of relativity space without ether is unthinkable” (p. 23).From our point of view, the major problem for recognition of the feasibility of LENR is the adopted quantum mechanical formalism. In quantum mechanics and particles physics, all elementary and subelementary particles are assumed spherical without any geometrical structure. Then the data interpretation of scattering experiments leads to a very small atomic nucleus on the order of a femtometer. This leads to a conclusion of a very strong Coulomb barrier that might be overcome only at temperatures of millions of degrees. The results from LENR experiments are in a sharp contrast to this consideration. According to BSM-SG theory, the physical models of protons and neutrons have superdense material structures with the shape of a folded and a twisted torus, respectively. They are much larger but thinner, so the Coulomb barrier also has a non-spherical shape and it is not so strong. The protons and neutrons are held in the nucleus by a Supergravitational (SG) field, which is behind the strong nuclear forces. The protons and neutrons in the atomic nuclei form three-dimensional fractal structures. The spatial geometry of the nuclear structures defines the row-column pattern of the periodic table with identifiable features of the valences, isotope stability, nuclear spin and chemical bond directions. The analysis leads to a hypothesis that the superdense nucleus causes a micro-curvature – a general relativistic effect around the nucleus. It has a feature of energy storage that corresponds to the mass deficit or nuclear binding energy expressed by Einstein's equation, E = mc^2. The fusion or fission reaction causes a small change of the micro-curvature, so the difference in the binding energy is released as gamma and particle radiation that is finally converted to heat.The analysis of some LENR experiments shows that the excited state of hydrogen and deuterium, known as the Rydberg state, facilitates some fusion reactions. According to BSM-SG, the Rydberg state is an ion-electron pair, with a finite size at the boundary of the SG field, while possessing a strong magnetic field due to the dominated magnetic moment of the electron. Additionally, the anomalous magnetic moment of the electron provides a constant driving momentum. When combined with a proper nuclear spin state of a selected heavier element, this momentum assists the magnetic field interactions, and this leads to nuclear fusion.

Book Description
This textbook was written because the authors failed to find a comprehensive text for a course on non-relativistic nuclear reactions. The book combines a thorough theoretical approach with applications to recent experimental results. The main formalisms used to describe nuclear reactions areexplained clearly and coherently, and the reader is led from basic laws to the final formulae used to calculate measurable quantities. Topics treated include quantal and semi-classical potential scattering, the formal theory of nuclear reactions, including the theory of the optical model, anddirect reactions and coupled-channel systems. Also included are compound nucleus reactions and fusion, dissipation fluctuations in deep-inelastic collisions, fusion, and heavy-ion induced fission. The book will be welcomed by lecturers, graduate students, and researchers in nuclear and atomicphysics.

Pages : 527
Book Description
The pursuit of nuclear fusion as an energy source requires a broad knowledge of several disciplines. These include plasma physics, atomic physics, electromagnetics, materials science, computational modeling, superconducting magnet technology, accelerators, lasers, and health physics. Nuclear Fusion distills and combines these disparate subjects to create a concise and coherent foundation to both fusion science and technology. It examines all aspects of physics and technology underlying the major magnetic and inertial confinement approaches to developing nuclear fusion energy. It further chronicles latest developments in the field, and reflects the multi-faceted nature of fusion research, preparing advanced undergraduate and graduate students in physics and engineering to launch into successful and diverse fusion-related research. Nuclear Fusion reflects Dr. Morse’s research in both magnetic and inertial confinement fusion, working with the world’s top laboratories, and embodies his extensive thirty-five year career in teaching three courses in fusion plasma physics and fusion technology at University of California, Berkeley.

Nuclear Lattice Effective Field Theory
Author: Timo A. Lähde
Publisher: Springer
ISBN: 3030141896
Category : Science
Languages : en
Pages : 400
Book Description
This primer begins with a brief introduction to the main ideas underlying Effective Field Theory (EFT) and describes how nuclear forces are obtained from first principles by introducing a Euclidean space-time lattice for chiral EFT. It subsequently develops the related technical aspects by addressing the two-nucleon problem on the lattice and clarifying how it fixes the numerical values of the low-energy constants of chiral EFT. In turn, the spherical wall method is introduced and used to show how improved lattice actions render higher-order corrections perturbative. The book also presents Monte Carlo algorithms used in actual calculations. In the last part of the book, the Euclidean time projection method is introduced and used to compute the ground-state properties of nuclei up to the mid-mass region. In this context, the construction of appropriate trial wave functions for the Euclidean time projection is discussed, as well as methods for determining the energies of the low-lying excitations and their spatial structure. In addition, the so-called adiabatic Hamiltonian, which allows nuclear reactions to be precisely calculated, is introduced using the example of alpha-alpha scattering. In closing, the book demonstrates how Nuclear Lattice EFT can be extended to studies of unphysical values of the fundamental parameters, using the triple-alpha process as a concrete example with implications for the anthropic view of the Universe. Nuclear Lattice Effective Field Theory offers a concise, self-contained, and introductory text suitable for self-study use by graduate students and newcomers to the field of modern computational techniques for atomic nuclei and nuclear reactions.
