CCC method: new applications to electron scattering from atoms and molecules. Achievement of the stated aims will be of enormous benefit to industry
and laboratory research because at the present time no reliably accurate
models exist for the range of the required scattering parameters. The
modelling work will result in development of new software packages for
supercomputers and will provide training for research associates, PhD

Summary
Ultra High Resolution Electron Recycling Spectrometer. Electron collisions with atoms and molecules provide enormous versatility through the transfer of large amounts of angular momentum and the ability to excite dipole forbidden states. However a lack of energy resolution severely restricts the processes that can be studied.
We propose to construct a unique, ultra-high resolution, electron recycling spectrometer using a radical new design. State-of-the-art spectroscopic studies of ato ....Ultra High Resolution Electron Recycling Spectrometer. Electron collisions with atoms and molecules provide enormous versatility through the transfer of large amounts of angular momentum and the ability to excite dipole forbidden states. However a lack of energy resolution severely restricts the processes that can be studied.
We propose to construct a unique, ultra-high resolution, electron recycling spectrometer using a radical new design. State-of-the-art spectroscopic studies of atoms and molecules will be enabled, including the dynamics of near-threshold processes, the formation of transient states and the examination of processes such as rotational excitation and dissociative attachment in molecules - important in a number of gas-discharge based devices.

It will also facilitate significant improvements in the accuracy of astrophysical and artificial plasma modelling, as well as providing insight into many processes fundamental to nanotechnology research. The research project will further enhance our reputation in an area where Australian theorists are preeminent, and the research training will produce PhD graduates with a high-level ability in numerical modelling using supercomputers. Such skills are essential in many defense, mining and technological applications of national priority.Read moreRead less
Novel collision experiments with metastable neon atoms in an atom trap. The aim of this project is to investigate collisions involving atoms in long lived excited states (metastable states). The project will utilise a magneto-optical trap to investigate electron-atom collisions as well as interatomic collisions for ultra-cold atoms. The outcomes of such investigations extend scientific knowledge of these important processes as a well as provide data for testing fundamental scattering theories.

Studies of turbulence and coherent structures in quasi two-dimensional plasmas and fluids. One of the most celebrated but least understood complex systems in nature is turbulent flow. This cross-disciplinary project aims to contribute to basic scientific knowledge of a class of turbulent flows, known as quasi two-dimensional fluids, that typically exhibit self-organizing properties, stable sheared flow, and relatively weak dissipation. The significance lies in the proposed testing, by modelling ....Studies of turbulence and coherent structures in quasi two-dimensional plasmas and fluids. One of the most celebrated but least understood complex systems in nature is turbulent flow. This cross-disciplinary project aims to contribute to basic scientific knowledge of a class of turbulent flows, known as quasi two-dimensional fluids, that typically exhibit self-organizing properties, stable sheared flow, and relatively weak dissipation. The significance lies in the proposed testing, by modelling and simulation studies, of the well-grounded hypothesis that suppression of turbulence by sheared flow is a universal phenomenon in such fluids, and that it can be exploited to control transport of fluid constituents. Applications of this new knowledge will be developed.Read moreRead less
Positronic Atoms - A Search for Positron Bound States. An experimental verification of positron bound states will solve a long standing problem in positron physics. A clear understanding of positron binding and the underlying mechanisms will open a new era in low-energy positron-atom/molecular physics, leading the way for breakthrough sciences. For instance, a positron bound state should enhance the annihilation rate between the positron and target valence electron.

A clear understanding of positron binding and the underlying mechanisms will open a new era in low-energy positron-atom/molecular physics, leading the way for breakthrough sciences. For instance, a positron bound state should enhance the annihilation rate between the positron and target valence electron. Positron annihilation, to produce two gamma rays, is a key process in both materials research (e.g. as already heavily employed in defect detection) and bio-medical treatments (e.g. the Positron Emission Tomography, or PET).Read moreRead less
