The study of positron collisions is an exciting branch of atomic scattering physics as it combines fundamentally unique processes and interactions, related to its antimatter nature, with the opportunity of deepening the basic understanding of collision physics in general (e.g. through the variation of change and mass of the projectile). Additionally, with the realisation of atomic beams of positronium (Ps), the bound state of an electron and a positron, a new branch of investigation has emerged. This latter type of research has been pioneered over the last decade at UCL where the only operational Ps beam in the world exists.In the case of positron impact, the proposed work is intended to clarify important outstanding problems such as the nature of (real and virtual) mechanisms resulting in ionisation and molecular fragmentation as well as interference and correlation effects in ionisation and other scattering channels. The proposed research also aims at extending the studies of Ps interactions to other atomic and molecular targets and at beginning to probe, for the first time, specific Ps scattering processes.This proposal, concerning important basic research and involving the training of young scientists, is consistent with the mission of EPSRC.
