Download or read book Pre equilibrium Nuclear Reactions written by Ettore Gadioli and published by . This book was released on 1992 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: While we have attempted to mention at least the most important developments in the theory of pre-equilibrium reactions, the volume of work in this area over the last few years has been so immense that it is not possible to give a comprehensive account of all that has been done. Our aim is to describe as clearly as we can the main physical ideas and to sketch the mathematical formulations that have been developed to enable practical calculations to be made. We attach particular importance to the detailed comparisons between theory and experiment because only in this way is it possible to assess the usefulness and validity of the theories that have been proposed.

Download or read book Mathematics and War written by Bernhelm Booß-Bavnbek and published by Birkhäuser. This book was released on 2012-12-06 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematics has for centuries been stimulated, financed and credited by military purposes. Some mathematical thoughts and mathematical technology have also been vital in war. During World War II mathematical work by the Anti-Hitler coalition was part of an aspiration to serve humanity and not help destroy it. At present, it is not an easy task to view the bellicose potentials of mathematics in a proper perspective. The book presents historical evidence and recent changes in the interaction between mathematics and the military. It discusses the new mathematically enhanced development of military technology which seems to have changed the very character of modern warfare.

Download or read book Quantum Theory of Finite Systems written by Jean-Paul Blaizot and published by Mit Press. This book was released on 1986 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive and pedagogical account of the various methods used in the quantum theory of finite systems, including molecular, atomic, nuclear, and particle phenomena. Covering both background material and advanced topics and including nearly 200 problems, Quantum Theory of Finite Systems has been designed to serve primarily as a text and will also prove useful as a reference in research. The first of the book's four parts introduces the basic mathematical apparatus: second quantization, canonical transformations, Wick theorems and the resulting diagram expansions, and oscillator models. The second part presents mean field approximations and the recently developed path integral methods for the quantization of collective modes. Part three develops perturbation theory in terms of both time-dependent Feynman diagrams and time-independent Goldstone diagrams. A fourth part discusses variational methods based on correlated wavefunctions, including spin correlations. The approximation schemes are formulated for fermions and bosons at eigher zero or non-zero temperature. Although the formalism developed applies to both finite and infinite systems, the book stresses those aspects of the theory that are specific to the description of finite systems. Thus special attention is given to mean field approximations, the ensuing broken symmetries, and the associated collective motions such as rotations. Conversely, some specific features of systems with infinite numbers of degrees of freedom (such as the thermodynamic limit, critical phenomena, and the elimination of ultraviolet divergencies) are deliberately omitted. Jean-Paul Blaizot and Georges Ripka are associated with the Centre d'Etudes Nucleaires de Saclay.
Download or read book Encyclopedia of Ancient Natural Scientists written by Paul T. Keyser and published by Routledge. This book was released on 2008-11-19 with total page 1468 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia of Ancient Natural Scientists is the first comprehensive English language work to provide a survey of all ancient natural science, from its beginnings through the end of Late Antiquity. A team of over 100 of the world’s experts in the field have compiled this Encyclopedia, including entries which are not mentioned in any other reference work – resulting in a unique and hugely ambitious resource which will prove indispensable for anyone seeking the details of the history of ancient science. Additional features include a Glossary, Gazetteer, and Time-Line. The Glossary explains many Greek (or Latin) terms difficult to translate, whilst the Gazetteer describes the many locales from which scientists came. The Time-Line shows the rapid rise in the practice of science in the 5th century BCE and rapid decline after Hadrian, due to the centralization of Roman power, with consequent loss of a context within which science could flourish.

Download or read book Microdosimetry written by Lennart Lindborg and published by CRC Press. This book was released on 2020-10-02 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental microdosimetry deals with the measurement of charged particle energy deposition in tissue equivalent volumes, ranging in size from nanometres to micrometres. Microdosimetry is employed to improve our understanding of the relationship between radiation energy deposition, the resulting biological effects, and the appropriate quantities to be used in characterizing and quantifying radiation quality. Although many reviews and contributions to the field have been published over the past fifty years, this new book is the first to provide a single, up to date, and easily accessible account of experimental microdosimetry. This book is designed to be used in medical, radiation, and health physics courses and by Master's and PhD students. In addition to serving as an introductory text to the field for graduate students, this book will also be of interest as a teaching and reference resource for graduate supervisors and established researchers. Drs. Lennart Lindborg and Anthony Waker have spent a life-time career in experimental microdosimetry research in academic, industrial and regulatory environments and have observed the development of the field from its early days as a recognized discipline; they bring to this book particular knowledge and experience in the design, construction, operation and use of tissue equivalent gas ionization counters and chambers.

Download or read book Random Matrices and the Statistical Theory of Energy Levels written by M. L. Mehta and published by Academic Press. This book was released on 2014-05-12 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Random Matrices and the Statistical Theory of Energy Levels focuses on the processes, methodologies, calculations, and approaches involved in random matrices and the statistical theory of energy levels, including ensembles and density and correlation functions. The publication first elaborates on the joint probability density function for the matrix elements and eigenvalues, including the Gaussian unitary, symplectic, and orthogonal ensembles and time-reversal invariance. The text then examines the Gaussian ensembles, as well as the asymptotic formula for the level density and partition function. The manuscript elaborates on the Brownian motion model, circuit ensembles, correlation functions, thermodynamics, and spacing distribution of circular ensembles. Topics include continuum model for the spacing distribution, thermodynamic quantities, joint probability density function for the eigenvalues, stationary and nonstationary ensembles, and ensemble averages. The publication then examines the joint probability density functions for two nearby spacings and invariance hypothesis and matrix element correlations. The text is a valuable source of data for researchers interested in random matrices and the statistical theory of energy levels.
Download or read book Neutron Capture Gamma Ray Spectroscopy written by R. E. Chrien and published by Springer. This book was released on 2011-12-29 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The post World War II era witnessed a tremendous growth in the research carried out in neutron-induced reactions and especially in neutron capture y-ray studies. This growth was stimulated by the availability of neutron sources, such as reactors and accelerators, and by the development of high resolution y-ray and conversion electron detectors. Today the combination of high flux reactors and precise instrumentation has produced spectral data of exceptional quality, as the pages of these proceedings illustrate. The world-wide community of the practioners of the art of cap ture y-ray spectroscopy has met three times in the last decade: the first international symposium on this subject was held at Studsvik, Sweden in 1969, and the second at Petten, The Netherlands in 1974. A smaller meeting, of mostly u. S. and some European parti cipation, was held at Argonne National Laboratory in 1966. A perusal of the proceedings of these meetings shows the striking ad vances in this now mature field of physics over the last dozen years. Each meeting has seen a small but perceptible increase in the number of papers presented and the number of laboratories repre sented. More importantly, each meeting has documented the increasing impact of (n,y) reasearch, not only on other areas of basic physics, but also on commercial and medical applications of this technology. A total of 29 invited papers and 97 contributed papers were presented at this symposium.

Download or read book Improbable Warriors written by Kathleen Broome Williams and published by US Naval Institute Press. This book was released on 2001 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the outbreak of World War II, four scientists left their comfortable college teaching positions to work for the government. Three served in uniform, the fourth oversaw contracts for the Navy. Such dramatic changes in life styles during the period were common -- for men. But these established scientists were women, and each made significant contributions to a Navy embroiled in a modern, science-dependent war. Mary Sears, a Woods Hole Oceanographic Institution planktonologist, headed the Hydrographic Office's Oceanographic Unit. Grace Hopper, a Yale-trained mathematician, went to the Bureau of Ships Computation Laboratory at Harvard where she worked on one of the first computers, churning out essential data for ordnance and other projects. Florence van Straten, a New York University chemist, served as an aerological engineer analyzing the use of weather in combat. Mina Rees was the chief technical aide to the applied mathematics panel of the National Defense Research Committee. This book firmly places the women within the context of their times. Deeply rooted in previously unexamined primary sources, the work helps readers understand the personal and professional experiences of women in the military and the attitudes they faced, and fully appreciate the educational and occupational barriers faced by women scientists in the 1930s and 1940s. The author focuses on their efforts during the war, but also discusses the women's skills and training, tells how they came to war work, and examines the contributions they made once there. She further considers how the war changed their lives, especially their professional lives, and how it affected their future careers. While other books havebeen written about women in the military, this is the first to focus on Navy women scientists.
Download or read book The Nucleon Optical Model written by Peter Edward Hodgson and published by World Scientific. This book was released on 1994 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nucleon optical model is widely used to calculate the elastic scattering cross-sections and polarisations for the interaction of neutrons and protons with atomic nuclei. The optical model potentials not only describe the scattering but also provide the wave functions needed to analyse a wide range of nuclear reactions. They also unify many aspects of nuclear reactions and nuclear structure. This book consists of a comprehensive introduction to the subject and a selection of papers by the author describing the optical model in detail. It contains full references to the original literature with many examples of the application of the model to the analysis of experimental data.
