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
This volume 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.

Book Description
This book presents details of electron impact single ionization of atoms and ions. The ionization of atoms and molecules by photon or charged particle impact such as electrons is of great importance in physics. Over the past several years a great progress has been made to understand the physics of electron impact single ionization processes (i.e. (e, 2e) processes) on atoms and ions and its quantum mechanically complete studies have also been performed. Theoretical investigations of (e, 2e) processes on atoms provide a platform to understand the collision dynamics and the characteristics of the targets by studying triple differential cross section (TDCS). Study of TDCS using the (e, 2e) technique is an important method to probe the dynamics of the ionization process and such data are strongly needed in the fields of astrophysics, controlled nuclear fusion, plasma physics etc. Chapter 1 of this book gives introduction of the electron impact ionization and the details of research work done so far has been described. The theoretical formalism has been described in detail in Chapter 2. Results of TDCS for various atomic and ionic targets have been presented in Chapter 3 and 4.

Book Description
The ionization of O2 was investigated by using charge exchange in a double mass spectrometer. The breakdown graph was constructed. A break in the electron impact ionization efficiency curve is explained as being due to ion- molecule reactions between excited O(+) ions formed in an ion-pair process, and O2. It is shown that the cross sections must be very small for the reaction O(+) (quadruplet-S) + O2 to O + O2(+) since the cross sections for the corresponding reaction with Si(+) are small. Implications for the aeronomy are discussed.

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.
