Summary on Grant Application Form |

The last couple of years have seen great interest worldwide in the investigation and understanding of coincidence fragmentation processes. A coincidence fragmentation process is one where a particle is fired at a target, ionises it and the fragments are detected in coincidence, with their energies and angles resolved. The resulting multiply differential cross section represents almost all that we can know about a scattering process quantum mechanically. It is proposed to theoretically model the triple differential cross section for an ion impact ionisation, for example for the proces p+H -> p+p+e using a time dependent close coupling formalism in particular an adapted version of the Basis Generator Method (BGM) combined with a novel multidimensional integration technique. The results will be compared with for example new generation experiments like COLTRIMS. There are several very good reasons for studying such processes: firstly, the understanding of the dynamics of these collisions are still in their infancy, only no, are experiments able to observe such delicate and subtle few body effects and present theories are easily stretched to their limit; secondly, once the dynamics of the ionisation process is fully understood, these coincident techniques will offer the possibility of an analytic tool that could be used to probe the structure of the target, be it an atom, molecule, thin film or surface. Theoretical development in this exciting and rapidly expanding field is much needed.
