Book Description
Electron EM reviews the theoretical and experimental work of the last 30 years on continuous electron emission in energetic ion-atom collisions. High incident energies for which the projectile is faster than the mean orbital velocity of the active electron are considered. Emphasis is placed on the interpretation of ionization mechanisms. They are interpreted in terms of Coulomb centers associated with the projectile and target nuclear fields which strongly interact with the outgoing electron. General properties of the two-center electron emission are analyzed. Particular attention is given to screening effects. A brief overview of multiple ionization processes is also presented. The survey concludes with a complete compilation of experimental studies of ionization cross sections.

Book Description
Coincidence measurements of charge transfer and simultaneous projectile electron excitation provide insight into correlated two-electron processes in energetic ion-atom collisions. Projectile excitation and electron capture can occur simultaneously in a collision of a highly charged ion with a target atom; this process is called resonant transfer and excitation (RTE). The intermediate excited state which is thus formed can subsequently decay by photon emission or by Auger-electron emission. Results are shown for RTE in both the K shell of Ca ions and the L shell of Nb ions, for simultaneous projectile electron loss and excitation, and for the effect of RTE on electron capture.

Book Description
The last decade has seen dramatic progress in the development of devices for producing mu1ticharged ions. Indeed it is now pos sible to produce any charge state of any ion right up through 92 fully-stripped uranium (U +). Equally dramatic progress has been achieved in the energy range of the available ions. As an example, fully-stripped neon ions have been produced in useable quantities with kinetic energies ranging from a few ev to more than 20 Gev. Interest in the atomic physics of multicharged ions has grown apace. In the fusion program, the spectra of these ions is an im portant diagnostic tool. Moreover the presence of mu1ticharged ions presents a serious energy loss mechanism in fusion devices. This fact has motivated a program to study the collision mech anisms involved. In another area, mu1ticharged ions are present in the solar corona and the interstellar medium and knowledge of their collision properties and spectra is essential to understand ing the astrophysics. Other possible applications are to x-ray lasers and heavy ion inertial fusion. On a more fundamental level, new possibilities for testing quantum electrodynamics with mu1ti charged ions have emerged.

Book Description
This book contains the invited lectures and contributed papers presented at the V International Conference on the Physics of Highly Charged Ions, which was held at the lustus-Liebig-Universi tat Giessen, 10-14 September 1990. This conference was the ftfth in a series -after Stockholm (1982), Oxford (1984), Groningen (1986) and Grenoble (1988) -to deal with a rapidly growing fteld, which comprises the spectroscopy of highly charged ions and their interactions with photons, electrons, atoms, ions, and solids. Most of the matter of the universe is in the ionized state. Investigations dealing with hot plasmas on earth have been greatly furthered by thermonuclear-fusion research. The increasing maturity of this programme has revealed the fundamental role of highly charged ions in fusion plasmas. Today, it is clear that a detailed knowledge of the production mechanisms of highly charged ions and their interactions with other plasma constituents is an important prerequisite for a better understanding of the microscopic and macroscopic plasma properties. The study of highly charged ions involves various branches of physics. It was the aim of the conference to bring together physicists working in atomic collisions and spectroscopy, in plasma physics and astrophysics, as well as in solid-state and ion-source physics. About 220 scientists from 20 nations attended the conference, indicating the strong worldwide interest and the vital ity of research in this fteld.

Book Description
Highly charged ions are the most chemically reactive species known to mankind. This reactivity is due to the extremely large potential energy they posses. This textbook deals with the wide range of interactions which occur when such ions interact with other forms of matter, especially solid surfaces and gasses. Particular emphasis is placed on situations where the kinetic energy associated with the interactions is small so that the effects of the high potential energy are most apparent. Experimental and theoretical techniques of investigation are covered in addition to the findings they produce. The treatment aims to be instructive to the beginner while leading on to a level where the newest findings are reviewed. As such the text is suitable for final year undergraduates, postgraduates or experienced researchers.

Book Description
It is arguable that most of chemistry and a large portion of atomic physics is concemed with the behaviour of the 92 naturally occurring elements in each of 3 charge states (+1, 0, -1); 276 distinct species. The world of multiply and highly charged ions provides a further 4186 species for us to study. Over 15 times as many! It is the nature of human beings to explore the unknown. This nature is par ticularly strong in physicists although this may not be readily apparent because theses explorations are undertaken in somewhat abstract 'spaces'. It is, then, no surprise that we have begun to explore the realm of multiply and highly charged ions. Over the past few decades, a consistent1y high quality body of work has emerged as the fruits of this exploration. This intemationally based subject, pursued in universities and research laboratories worldwide, has ex panded beyond its roots in atomic physics. We now see it embracing elements of surface science, nuclear physics and plasma physics as well as drawing on a wide range of technologies. This speciality offers new tests of some of our most fundamental ideas in physics and simultaneously new medical cures, new ways of fabricating electronic gadgets, a major hope for clean sustainable energy and explanations for astrophysical phenomena. It is both a deeply fundamental and a widely applicable area of investigation.
