Atomic tests of unification theories. Although the standard model of particle physics has withstood decades of intensive experimental tests, it is widely believed to be merely a low-energy manifestation of a "true" theory that unifies the four forces of nature. While some searches for new physics beyond the standard model are performed at high-energy particle accelerators, a very sensitive probe can be done at low energies in atomic and molecular measurements of weak interaction effects. This pr ....Atomic tests of unification theories. Although the standard model of particle physics has withstood decades of intensive experimental tests, it is widely believed to be merely a low-energy manifestation of a "true" theory that unifies the four forces of nature. While some searches for new physics beyond the standard model are performed at high-energy particle accelerators, a very sensitive probe can be done at low energies in atomic and molecular measurements of weak interaction effects. This project is devoted to a theoretical investigation of weak interaction effects in atoms, molecules, and nuclei. It will provide improved tests of unified theories.Read moreRead less
Characterising Nuclei Far from Stability With a Novel Recoil Spectrometer. A high sensitivity detector system for use in conjuction with a superconducting solenoidal transporter will be developed for gamma-ray and conversion spectroscopy of neutron-deficient nuclei. The technology will be optimised for near-symmetric heavy ion reactions and applied initially to the characterisation of shape co-existence in the light lead isotopes.

Personnel in space, aviation, and terrestrial applications may be exposed to potentially harmful levels of densely ionising radiation. This project will produce improved radiation detectors and computational techniques, addressing needs in the prediction and assessment of equivalent dose in these applications. The "preventative healthcare" priority goal of the National Research Priority "Promoting and Maintaining Good Health" will be addressed, serving to reduce the risk to personnel involved in such activities. This research will also enhance Australia's international reputation in this field, stimulate local expertise, and create a critical mass of researchers in this field. Read moreRead less
Searching for Supersymmetry in the Universe with the A Toroidal Lagre Hadron Collider ApparatuS (ATLAS) experiment at the Large Hadron Collider. Australian researchers have been involved with the A Toroidal Lagre Hadron Collider ApparatuS (ATLAS) experiment at the Large Hadron Collider since the early 1990's.

Australian researchers have been involved with the A Toroidal Lagre Hadron Collider ApparatuS (ATLAS) experiment at the Large Hadron Collider since the early 1990's. They have had significant roles in ATLAS hardware design and construction, software development, and in the deployment of a data computing grid, thereby paving the way for groundbreaking discoveries surrounding the fundamental laws and origin of our universe. By performing a search for Higgs bosons, required in many models of particle physics but which have so far not been observed, this research embodies the final step on this road to discovery. The huge publicity surrounding the discovery potential at the Large Hadron Collider will raise the international awareness and stature of basic research in Australia.Read moreRead less
Alpha-particle cluster structure in light nuclei: helping and hindering fusion? A new, efficient detector system will be designed and built to answer a question never before asked - can the special structures of carbon, resembling three alpha-particles, assist rather than hinder the process of fusion with heavy nuclei? This question has arisen through my recent work published in Nature, which showed that in reactions with heavy nuclei, paradoxically both fusion and break-up into alpha-particles ....Alpha-particle cluster structure in light nuclei: helping and hindering fusion? A new, efficient detector system will be designed and built to answer a question never before asked - can the special structures of carbon, resembling three alpha-particles, assist rather than hinder the process of fusion with heavy nuclei? This question has arisen through my recent work published in Nature, which showed that in reactions with heavy nuclei, paradoxically both fusion and break-up into alpha-particles are more likely for carbon than for neighbouring nuclei. These results defy interpretation within the standard theory of nuclear fusion. The project will help to maintain Australia's world-leading position in the study of nuclear fusion.
