Atomic Collision Theory. Collisions between atomic particles are ever-present in astrophysical and man-made plasmas. Their understanding is vital for both fundamental science and industrial applications. The project will develop underlying scattering theory to solve new and outstanding problems in the field. These range from the fundamental problems of electron- or proton-impact ionisation of hydrogen through to collisions involving targets of interest to astrophysics, fusion, X-ray lasers and t ....Atomic Collision Theory.

The project will develop underlying scattering theory to solve new and outstanding problems in the field. These range from the fundamental problems of electron- or proton-impact ionisation of hydrogen through to collisions involving targets of interest to astrophysics, fusion, X-ray lasers and the lighting industry. The theory will also be extended to atom-surface interactions. The understanding of collisions between atomic particles and surfaces will support emerging fields of nanoscience and quantum computing.

Matter-antimatter interactions. Much of the light that we see is either due to or is influenced by collisions between particles on the atomic scale. The understanding of astronomical observations, the Sun, or our atmosphere is underpinned by the knowledge of atomic collisions. They are also critical in the development of fusion, lasers and lighting sources generally. Interactions with antimatter have additional applications in the medical and material sciences.

Uncovering highly excited states of quantum three body systems using new technological approaches. Experimental studies of the fundamental structure of quantum three body systems are proposed to uncover long-lived highly-excited states. Ultra-fast timing technology applied to a variant of electron time-of-flight studies will form the basis of the measurement system to be used at a world-class synchrotron light source.
Atomic Ionization on the Attosecond Time Scale. Electrons emit light, carry electric current, and bind atoms together to form molecules. Insight into their atomic-scale motion is the key to understanding the functioning of biological systems, developing efficient sources of x-ray light, and speeding up electronics. Capturing this electron motion requires attosecond (one quintillionth of a second) time resolution.
