Theory of Electron-Atom Collisions Part 1 Potential Scattering


Free Download Theory of Electron-Atom Collisions: Part 1: Potential Scattering By Philip G. Burke, Charles J. Joachain (auth.)
1995 | 255 Pages | ISBN: 1489915699 | PDF | 9 MB
The authors aim to hone the theory of electron-atom and electron-ion collisions by developing mathematical equations and comparing their results to the wealth of recent experimental data. This first of three parts focuses on potential scattering, and will serve as an introduction to many of the concepts covered in Parts II and III. As these processes occur in so many of the physical sciences, researchers in astrophysics, atmospheric physics, plasma physics, and laser physics will all benefit from the monograph.

Electron Emission in Heavy Ion-Atom Collisions


Free Download Electron Emission in Heavy Ion-Atom Collisions By Priv.-Doz. Dr. Nikolaus Stolterfoht, Professor Robert D. DuBois, Professor Roberto D. Rivarola (auth.)
1997 | 246 Pages | ISBN: 3642083226 | PDF | 7 MB
Electron Emission in Heavy-Ion–Atom Collisions reviews the theoretical and experimental work of the last 30 years on continuous electron emission in energetic ion-atom collisions. Emphasis is placed on the interpretation of ionization mechanisms. These mechanisms are interpreted in terms of Coulomb centers associated with the projectile, and target nuclear fields, which strongly interact with bare projectiles, are treated as cases for single-projectile and target centers. General properties of the two-center electron emission are analyzed with electron capture to the continuum and saddle-point electron emission as specific examples. For dressed projectiles, particular attention is devoted to screening effects, anomalies in the binary-encounter peak production, diffraction effects, and dielectronic processes involving two active electrons. A brief overview of multiple ionization processes is also presented. The survey concludes with a complete compilation of experimental studies of ionization cross sections.

The Nuclear Axis Germany, Japan and the Atom Bomb Race 1939-45


Free Download Philip Henshall – The Nuclear Axis: Germany, Japan and the Atom Bomb Race 1939-45
Sutton Publishing | 2000 | ISBN: 0750922931 | English | 264 pages | PDF | 161.51 MB
It has been generally accepted that Germany and Japan were years behind the Allies in producing a nuclear weapon during World War II and that Japan in particular was technically incapable of doing so. The author argues that these assumptions are unfounded and reveals that an Axis nuclear weapon was a very real threat to the Allies. Philip Henshall begins by outlining how Germany’s conventional military situation began to deteriorate from 1943 onwards, how interest was revived in secret long-range weapons, and how SS General Kammler assumed virtually complete control of all long-range weapons projects. The origin of weapons in Germany is examined, with parallel references to the USA’s Manhattan Project and, Henshall puts forward his theory that the leading figure in German nuclear science, Heisenberg, knew what was required to build an atomic bomb and fully understood the physics of the device – contrary to the accepted version of events.

The Nature of the Atom An Introduction to the Structured Atom Model


Free Download The Nature of the Atom: An Introduction to the Structured Atom Model by J.E. Kaal, J.A. Sorensen, A. Otte
English | September 1, 2021 | ISBN: 1838128026 | 300 pages | PDF | 12 Mb
This book is the result of an international research team pursuing the intuitive notion that the atomic nucleus should have structural properties. Starting with a few logical assumptions, they discovered that many properties of the atom and the nucleus can be explained rationally without resorting to quantum mechanics or the limiting dogmas about the nucleus that dominate current physics. Using feedback from known experimental data, they identified several organizational principles that nature appears to use for constructing the elements, sometimes in unexpected ways.

RSS and Atom in Action Web 2.0 Building Blocks


Free Download RSS and Atom in Action: Web 2.0 Building Blocks by Dave Johnson
English | 2006 | ISBN: 1932394494 | 300 Pages | PDF | 12.3 MB
An innovator’s guide to application development with blog, wiki, and newsfeed technologies, this book introduces the new ways of collaboration enabled by these technologies and focuses on the fundamental concepts needed to understand how the technologies can be used in real world applications. Blog and wiki server internals are covered in depth, and newsfeed formats and web service protocols for blogging are covered from a developer’s point-of-view. Also covered are a variety of techiques programmers can use to monitor blog conversations, such as newsfeed search engines, and ways to join in the conversation such as comments, trackbacks, and Weblogs.com pings. Examples in Java and C# are provided to show how to parse Atom and RSS format newsfeeds, how to generate valid newsfeeds, how to serve them efficiently, and how to automate blogging via web services based on the new Atom protocol and the older MetaWeblog API. Focus is given to more than a dozen blog apps-small but immediately useful example applications based on blog, wiki, and newsfeed technologies.

Neutral-atom Astronomy Plasma Diagnostics From The Aurora To The Interstellar Medium (Advances In Planetary Science)


Free Download Neutral-atom Astronomy: Plasma Diagnostics From The Aurora To The Interstellar Medium (Advances In Planetary Science) by Ke Chiang Hsieh, Eberhard Mobius
English | May 23, 2022 | ISBN: 9813279192 | 328 pages | MOBI | 18 Mb
Astronomy has been associated with the detection of electromagnetic waves or photons from within and beyond the solar system, ranging from Radio to Gamma-ray Astronomy. Particle Astrophysics, including Neutrino and Dark-Matter Astrophysics today, started with the discovery of cosmic rays in 1911. The Space Age expanded particle observations to in-situ studies of lower energy electrons and ions with a variety of charge states in space plasmas traversed by spacecraft. Remote observation of space plasmas became possible only after the discovery of energetic neutral atoms (ENAs) in space in 1950. This book is a primer for those who wish to learn more about the origins of ENAs, related detection techniques, and how ENA images and spectra can be used to study space plasmas beyond the reach of spacecraft. It tells a comprehensive story from the first encounters with ENAs in the Earth’s magnetosphere to Neutral-Atom Astronomy of the edge of the heliosphere and the interstellar medium. This story includes how ion mass spectrographs evolved into ENA imagers, overcoming the technical challenges, how to extract information from ENA data, and a variety of diagnostic applications on the magnetosphere, interplanetary space, other solar-system objects, the heliospheric boundary, the local interstellar medium, and a glimpse into the future of Neutral-Atom Astronomy. The authors hope to inform and inspire readers to further enrich this field of study.
