XV International Workshop on Low Energy Positron and Positronium Physics

Abstract

This volume of Journal of Physics: Conference Series contains the Proceedings of the XV International Workshop on Low Energy Positron and Positronium Physics, which was held at York University, Toronto, Canada, between 29 July and 1 August 2009. This Workshop was one of the official satellites of the XXVI International Conference on Photonic, Electronic and Atomic Collisions, held at Kalamazoo, MI, USA between 22 and 28 July 2009. Our Workshop was run in parallel with the XVI International Conference on Electron-Molecule Collisions and Swarms, enabling delegates to select talks from either meeting. The proceedings of the XVI International Conference on Electron-Molecule Collisions and Swarms are being published in a separate volume of Journal of Physics: Conference Series.The combined attendance at the two meetings was 110, from 19 countries, with interest being roughly split between the two areas. There were 5 plenary lectures addressed to all participants and on the Positron Workshop side there were 20 invited talks and 40 posters presented in two poster sessions. The subjects covered antihydrogen, positron collisions with atoms and molecules, annihilation, bound and resonant states, positronium and positronium negative ion, plasmas and swarms. The talks and posters highlighted the vigour of the field and underlined the impressive new developments now in progress and which promise to transform the subject.The next Workshop of this biennial series of meetings will be held in July 2011 at Maynooth University in Ireland.R I Campeanu J W Darewych A D Stauffer Guest Editors
