 Free Download Atoms, Molecules and Photons: An Introduction to Atomic- Molecular- and Quantum Physics by Wolfgang Demtröder English | PDF (True) | 2006 | 578 Pages | ISBN : 3540206310 | 10.2 MB This introduction to Atomic and Molecular Physics explains how our present model of atoms and molecules has been developed during the last two centuries by many experimental discoveries and from the theoretical side by the introduction of quantum physics to the adequate description of micro-particles. It illustrates the wave model of particles by many examples and shows the limits of classical description. The interaction of electromagnetic radiation with atoms and molecules and its potential for spectroscopy is outlined in more detail and in particular lasers as modern spectroscopic tools are discussed more thoroughly. Many examples and problems with solutions should induce the reader to an intense active cooperation.  Free Download Atoms and Molecules in Strong External Fields by P. Schmelcher, W. Schweizer English | PDF | 2002 | 330 Pages | ISBN : 030645811X | 10.3 MB This book contains contributions to the 172. WE-Heraeus-Seminar "Atoms and Molecules in Strong External Fields," which took place April 7-11 1997 at the Phys- zentrum Bad Honnef (Germany). The designation "strong fields" applies to external static magnetic, and/or electric fields that are sufficiently intense to cause alterations in the atomic or molecular str- ture and dynamics. The specific topics treated are the behavior and properties of atoms in strong static fields, the fundamental aspects and electronic structure of molecules in strong magnetic fields, the dynamics and aspects of chaos in highly excited R- berg atoms in external fields, matter in the atmosphere of astrophysical objects (white dwarfs, neutron stars), and quantum nanostructures in strong magnetic fields. It is obvious that the elaboration of the corresponding properties in these regimes causes the greatest difficulties, and is incomplete even today. Present-day technology has made it possible for many research groups to study the behavior of matter in strong external fields, both experimentally and theore- cally, where the phrase "experimentally" includes the astronomical observations. - derstanding these systems requires the development of modern theories and powerful computational techniques. Interdisciplinary collaborations will be helpful and useful in developing more efficient methods to understand these important systems. Hence the idea was to bring together people from different fields like atomic and molecular physics, theoretical chemistry, astrophysics and all those colleagues interested in aspects of few-body systems in external fields.  Free Download Atomic and Quantum Physics: An Introduction to the Fundamentals of Experiment and Theory by Hermann Haken , Hans Christoph Wolf English | PDF | 1984 | 402 Pages | ISBN : 3642968155 | 37 MB A thorough knowledge of the physics of atoms and quanta is clearly a must for every student of physics but also for students of neighbouring disciplines such as chemistry and electrical engineering. What these students especially need is a coherent presenta tion of both the experimental and the theoretical aspects of atomic and quantum physics. Indeed, this field could evolve only through the intimate interaction between ingenious experiments and an equally ingenious development of bold new ideas. It is well known that the study of the microworld of atoms caused a revolution of physical thought, and fundamental ideas of classical physics, such as those on measur ability, had to be abandoned. But atomic and quantum physics is not only a fascinating field with respect to the development of far-reaching new physical ideas. It is also of enormous importance as a basis for other fields. For instance, it provides chemistry with a conceptual basis through the quantum theory of chemical bonding. Modern solid-state physics, with its numerous applications in communication and computer technology, rests on the fundamental concepts first developed in atomic and quantum physics. Among the many other important technical applications we mention just the laser, a now widely used light source which produces light whose physical nature is quite different from that of conventional lamps. In this book we have tried to convey to the reader some of the fascination which atomic and quantum physics still gives a physicist studying this field.  Free Download Atomic Photoeffect by M. Ya. Amusia English | PDF | 1990 | 320 Pages | ISBN : 0306435489 | 29.7 MB This book is devoted to the investigation of a rather prevalent process in nature: interaction of atoms with electromagnetic radiation. Primary attention is given to the low and intermediate photon energy region, from tens to hundreds of electron-volts. It is in this region that the probability of photon absorption and photoionization is largest. Data in this energy region are very interesting and useful in astrophysics and plasma physics, solid-state physics and quantum electronics, and in a number of other branches of science and technical applications. Formulae for hydrogen atom photoionization are given in almost all textbooks on quantum mechanics. Together with the limited amounts of experimental data available up to the beginning of the sixties, the formulae gave an impression of the completeness of the study of photoionization, of the absolute clarity of the mechanism of the process, and of the possibility of calculating rather easily its probability using the formulae.  Free Download Atomic Inner-Shell Physics by Bernd Crasemann English | PDF | 1985 | 760 Pages | ISBN : 146129472X | 61.6 MB The physics of atomic inner shells has undergone significant advances in recent years. Fast computers and new experimental tools, notably syn chrotron-radiation sources and heavy-ion accelerators, have greatly enhan ced the scope of problems that are accessible. The level of research activity is growing substantially; added incentives are provided by the importance of inner-shell processes in such diverse areas as plasma studies, astrophysics, laser technology, biology, medicine, and materials science. The main reason for all this exciting activity in atomic inner-shell physics, to be sure, lies in the significance of the fundamental problems that are coming within grasp. The large energies of many inner-shell processes cause relativistic and quantum-electrodynamic effects to become strong. Unique opportunities exist for delicate tests of such phenomena as the screening of the electron self-energy and the limits of validity of the present form of the frequency-dependent Breit interaction, to name but two. The many-body problem, which pervades virtually all of physics, presents somewhat less intractable aspects in the atomic inner-shell regime: correlations are relatively weak so that they can be treated perturbatively, and the basic potential is simple and known! The dynamics of inner-shell processes are characterized by exceedingly short lifetimes and high transition rates that strain perturbation theory to its limits and obliterate the traditional separation of excitation and deexcitation. These factors are only now being explored, as are interference phenomena between the various channels.  Free Download Zachary Keck, "Atomic Friends: How America Deals with Nuclear-Armed Allies" English | ISBN: 1538169703 | 2022 | 296 pages | EPUB, PDF | 549 KB + 2 MB Should the United States prevent additional allies from developing atomic weapons? Although preventing U.S. allies and partners from acquiring nuclear weapons was an important part of America's Cold War goals, in the decades since, Washington has mostly focused on preventing small adversarial states from building the bomb. This has begun to change as countries as diverse as Germany, Japan, South Korea, Turkey, and Saudi Arabia, among others, have begun discussing the value of an independent nuclear arsenal. Their ambitions have led to renewed discussion in U.S. foreign policy circles about the consequences of allied proliferation for the United States. Even though four countries have acquired nuclear weapons, this discussion remains abstract, theoretical, and little changed since the earliest days of the nuclear era.  Free Download Cai Shen, "Atomic Force Microscopy for Energy Research (Emerging Materials and Technologies)" English | 2022 | ISBN: 103200407X | PDF | pages: 457 | 51.5 mb Atomic force microscopy (AFM) can be used to analyze and measure the physical properties of all kinds of materials at nanoscale in the atmosphere, liquid phase, and ultra-high vacuum environment. It has become an important tool for nanoscience research. In this book, the basic principles of functional AFM techniques and their applications in energy materials―such as lithium-ion batteries, solar cells, and other energy-related materials―are addressed.  Free Download Atomic Collisions in Solids: Volume 2 by Sheldon Datz, B. R. Appleton, C. D. Moak English | PDF | 1975 | 450 Pages | ISBN : 1461589983 | 46.1 MB Perhaps the most controversial aspeat of this volume is the number (V) assigned to the aonferenae in this series. Actually, the first aonferenae to be held under the title '~tomia Collisions in Solids" was held at Sussex University in England in 1969 and the seaond at Gausdal, Norway in 19?1, whiah would logically make the aonferenae held at Gatlinburg, Tennessee, U. S. A. in 19?3 the third (III). However, the appearance of the proceedings of the 19?1 Gausdal Conference (published by Gordon and Breaahj bore the number IV. The reasoning behind this was that, in. faat, two pre- vious aonferenaes had been largely dedicated to the same subjeat area. The first of these was at Aarhus, Denmark in 1965 and the seaond in 196? was held in Chalk River, Canada. Henae, the number V for the 19?3 meeting. Actually, the aonferenae aan easily be traaed baak to Paris, Franae in 196l when it went under the colorful title of '~e Bom- bardement Ionique. " In 1962 a small aonferenae was held at Oak Ridge, Tennessee, U. S. A. at whiah the discovery of channeling was first formally annunciated. This was followed by aonferenaes at Chalk River, Canada in 1963 and at Harwell, England in 1964. More- over, immediately following the Chalk River conference in 196? there was a aonferenae on higher energy collisions at Brookhaven, New York, U. S. A. Thus, strictly speaking, the Gatlinburg meeting is the tenth (X) in the series.  Free Download Boris Dorschel, Andrew J. Wheeler, Xavier Monteys, "Atlas of the Deep-Water Seabed: Ireland" English | 2011 | pages: 167 | ISBN: 904819377X, 9048193753 | PDF | 44,6 mb Presented in an accessible, user-friendly format, this atlas sets out all the major features revealed during one of the largest ever deep-sea mapping campaigns. A unique insight into the morphology of the seabed along the continental margin of the North-East Atlantic, it reveals for the first time many features that have hitherto been hidden beneath the waves. It is organised both thematically and by region, with the sea floor and its biological hotspots - areas of high biodiversity such as seamounts - shown at a resolution not possible before. The atlas presents everything from submarine canyons to coral carbonate mounds, using digital terrain models generated from multibeam data and photographs taken from unmanned deep-water vehicles (ROVs).
