Book Description
Electron and Photon Impact Ionization and Related Topics 2004 provides an overview of the latest advances in the field of ionization by electron and photon impact. The book contains 18 contributions of recent experimental, theoretical, and computational work on correlated processes that involve a wide range of targets, including atoms, molecules, clusters, and surfaces. It covers a broad range of current topics, such as multi-particle coincidence studies, in particular, (e,2e) and (e,3e) processes, photoionization with or without excitation, and multiphoton single and double ionization. Three chapters contain the following topics: anisotropy and polarization in Auger-electron emission, multiple ionization of atoms in strong fields, and theoretical and practical aspects of photoionization with excitation. Because of the extensive array of applications discussed, this book is an essential reference for chemists, biologists, and researchers working in atomic, molecular, cluster, and surface physics.

Book Description
Electron and Photon Impact Ionisation and Related Topics 2002 provides an overview of recent international research in the field of ionization by electron and photon impact. Emphasizing multi-particle coincidence studies, such as (e,2e), (e,3e), ionization-excitation, and double photo-ionization, the book contains 18 contributions of recent experimental, theoretical, and computational achievements in the realization, interpretation, and modeling of correlated processes that involve a wide range of targets, including atoms, molecules, and surfaces. It also covers nuclear reactions and interaction of electrons, photons, and ions with biological matter. This book is an essential reference for researchers working in atomic and molecular physics, surface science, chemistry, and biophysics.

Book Description
The great advantage of coincidence measurements is that by suitable choice of the kinematical and geometrical arrangement one may probe delicate physical effects which would be swamped in less differential experiments. The measurement of the triple dif ferential and higher-order cross sections presents enormous technical difficulties, but refined experiments of this type provide an insight into the subtleties of the scattering process and offer a welcome, if severe, test of the available theoretical models. The last few years have been an exciting time to work in the field and much has been learned. Profound insights have been gleaned into the basic Coulomb few body problem in atomic physics: the experimental study of the fundamental (e,2e) processes on hydrogen and helium targets continues to add to our knowledge and indeed to challenge the best of our theoretical models; significant advances have been made in the understanding of the "double excitation problem," that is the study of ionization processes with two active target electrons: important measurements of (e,3e), (,),,2e), excitation-ionization and excitation autoionization have been reported and strides have been made in their theoretical description; the longstanding discrepancies between theory and experiment for relativistic (e,2e) processes were resolved, spin dependent effects predicted and ob served and the first successful coincidence experiments on surfaces and thin films were announced. Theory and experiment have advanced in close consort. The papers pre sented here cover the whole gambit of research in the field. Much has been achieved but much remains to be done.

Book Description
The content of this book describes in detail the results of the present measurements of the partial and total doubly differential cross sections for the multiple-ionization of rare gas atoms by electron impact. These measurements show, beside other trends, the role of Auger transitions in the production of multiply ionized atoms in the region where the incident electron energy is sufficient to produce inner shell ionization. Other processes like Coster-Kronig transitions and shake off also contribute towards increasing the charge of the ions. The incident electron having energy of 6 keV, for example, in a collision with xenon atom can remove up to nine electrons! (*) X-ray-ion coincidence spectroscopy of the electron xenon atom collisions is also described. The present measurements of doubly differential cross sections for the dissociative and non-dissociative ionization of hydrogen, sulfur dioxide and sulfur hexa fluoride molecular gases by electron impact are also described in the text of this book. The results of the measurements for sulfur dioxide molecule show how this major atmospheric pollutant can be removed from the atmosphere by electron impact dissociation of this molecule. The present results of the measurements for sulfur hexa fluoride give an insight into the dissociation properties of this molecular gas, which is being so widely used as a gaseous insulator in the electrical circuits. The book also describes the present measurements of the polarization parameters of the fluorescence radiation emitted by the electron-impact-excited atoms of sodium and potassium. In these investigations the target atoms are polarized, therefore, the measurements of the polarization parameters give information about the electron atom interaction in terms of the interference, direct and exchange interaction channels.

Book Description
The proceedings contain lectures and contributed papers presented at the Latin American School of Physics in Caxambu, Brazil. Topics are related to a review of collision processes, excitation and ionization of molecules, ion formation by electron impact, mass and energy spectroscopy in collision reactions, desorption induced by ion and electron beams, and principles and applications of synchrotron radiation. The major theme of the school was “Current methods in collision processes.”

Book Description
This proceedings volume contains the invited talks presented at two atomic physics symposia held jointly in Buenos Aires, Argentina from 28-30 July 2005. All papers were peer-reviewed. They represent the latest research in dynamics of collision systems involving collisions between photons, electrons, and ions and a diverse range of target species: atoms, molecules, clusters, and surfaces. There is a particular emphasis on correlation and many-body effects in excitation and ionization.

Book Description
It is perhaps surprising that a process which was one of the first to be studied on an atomic scale, and a process which first received attention over seven decades ago, continues to be the object of diverse and intense research efforts. Such is the case with the (seemingly) conceptually simple and familiar mechanism of electron impact ionization of atoms, molecules, and ions. Not only has the multi-body nature of the collision given ground to theoretical effort only grudgingly, but also the variety and subtlety of processes contributing to ionization have helped insure that progress has come only with commensurate work: no pain - no gain. Modern experimental methods have made it possible to effectively measure and explore threshold laws, differential cross sections, partial cross sections, inner-shell ionization, and the ionization of unstable species such as radicals and ions. In most instances the availability of experimental data has provided impetus and guidance for further theoretical progress.

Book Description
Nanostructuring of materials is a task at the heart of many modern disciplines in mechanical engineering, as well as optics, electronics, and the life sciences. This book includes an introduction to the relevant nonlinear optical processes associated with very short laser pulses for the generation of structures far below the classical optical diffraction limit of about 200 nanometers as well as coverage of state-of-the-art technical and biomedical applications. These applications include silicon and glass wafer processing, production of nanowires, laser transfection and cell reprogramming, optical cleaning, surface treatments of implants, nanowires, 3D nanoprinting, STED lithography, friction modification, and integrated optics. The book highlights also the use of modern femtosecond laser microscopes and nanoscopes as novel nanoprocessing tools.
