Download or read book Dynamic Screening and Wake Effects on Electronic Excitation in Ion solid and Ion surface Collisions written by and published by . This book was released on 1991 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The collective electronic response in a solid effectively alters ionic and atomic potentials giving rise to dynamic screening and to a wake'' of density fluctuations trailing ions as they propagate through the solid. The presence of dynamic screening modifies electronic excitation processes of projectiles in ion-solid collisions as compared to binary ion-atom collisions. We review recent theoretical and experimental studies directed at the search for and identification of signatures of dynamic screening and wake effects. Examples include the formation of excited projectile bound states under channeling conditions, radiative electron capture, the search for wake riding'' electrons in antiproton-solid collisions, and the neutralization of highly charged ions near surfaces. 42 refs., 7 figs.

Download or read book Inelastic Ion Surface Collisions written by N Tolk and published by Elsevier. This book was released on 2012-12-02 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inelastic Ion-Surface Collisions is a collection of papers presented at the 1976 International Workshop on Inelastic-Ion-Surface Collisions, held at Bell Laboratories, Murray Hill, New Jersey. This book contains 12 chapters and begins with the identification and study of the underlying physical mechanisms associated with ionization, neutralization, and excitation responsible for the observed sputtering and particle backscattering outershell inelastic collision phenomena. Other chapters discuss the role of the bulk, the surface, and the near surface interaction regions on the degree of ionization, neutralization, and excitation. The remaining chapters deal with the oscillations in the energy dependence of backscattered ions, wake riding states, and optical polarization effects from beam transmission through tilted foils and from beam particle bombardment of surfaces at grazing incidence. This book is of great value to atomic, solid state, nuclear, surface, chemical, and space physicists.

Download or read book Electronic Excitations in Fast Ion solid Collisions written by and published by . This book was released on 1990 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: We review recent developments in the study of electronic excitation of projectiles in fast ion-solid collisions. Our focus will be primarily on theory but experimental advances will also be discussed. Topics include the evidence for velocity-dependent thresholds for the existence of bound states, wake-field effects on excited states, the electronic excitation of channeled projectiles, transport phenomena, and the interaction of highly charged ions with surfaces. 44 refs., 14 figs.
