This volume contains contributions covering a wide range of subjects in the area of photonic, electronic and atomic collisions. These include the collisions of heavy particles and electrons with atoms, molecules and clusters; the coherent control of reaction dynamics using lasers and electromagnetic fields with molecules, clusters and liquids; recent experimental progress in the synthesis of antihydrogen; the interaction of solar winds with cometary atmospheres, and the physical interpretation of reactions in biological systems.Contents: Angle-Resolved Photoelectrons as a Probe of Strong-Field Interactions (M Vrakking)Double and Triple Photoionization of Li and Be (J Colgan et al.)Multidimensional Photoelectron Spectroscopy (P Lablanquie et al.)Photoionizing Ions Using Synchrotron Radiation (R Phaneuf)Spin-Resolved Collisions of Electrons with Atoms and Molecules (G F Hanne)Electron Collisions with Trapped, Metastable Helium (L J Uhlmann et al.)Electron Driven Processes in Atmospheric Behavior (L Campbell et al.)Atomic Collisions Involving Positrons (H R J Walters & C Starret)Molecular Effects in Neutrino Mass Measurements (N Doss et al.)Atom-Diatom Collisions at Cold and Ultra-Cold Temperatures (F D Colavecchia et al.)Crystal Assisted Atomic Physics Experiments Using Heavy Ions (K Komaki)Fragmentation of Collisionally Excited Fullerenes (M Alcamí et al.)Fragmentation of Small Carbon Clusters (M Chabot et al.)and other papersReadership: Researchers and post-graduate students in atomic, molecular and optical physics.
