Laboratory studies of Nucleosynthesis via Accelerator Mass Spectrometry. This project aims at laboratory studies of stellar nucleosynthesis applying ultra-sensitive accelerator mass spectrometry (AMS) measurements. The project will focus on reactions which are essential to open questions in modelling nucleosynthesis in stars, that is where no data exist at all, or are scarce and discrepant; in particular for neutron- and charged-particle induced reactions relevant to the s-and p-process where an ....Laboratory studies of Nucleosynthesis via Accelerator Mass Spectrometry. This project aims at laboratory studies of stellar nucleosynthesis applying ultra-sensitive accelerator mass spectrometry (AMS) measurements. The project will focus on reactions which are essential to open questions in modelling nucleosynthesis in stars, that is where no data exist at all, or are scarce and discrepant; in particular for neutron- and charged-particle induced reactions relevant to the s-and p-process where an extremely sensitive detection method is required. New data for key nuclear reactions will be connected with theory, for testing and improving theoretical predictions. They will be highly beneficial for modelling the respective nucleosynthesis processes in stars and for our understanding of the elemental abundance of our solar system.Read moreRead less
Creating superheavy elements and isotopes. This project aims to measure properties, probabilities and timescales of competing quasifission processes, by combining Australian accelerator and detector capabilities with exotic radioactive targets. In 2015, nuclear fusion created superheavy elements with atomic numbers 113 to 118. The race is now on to create elements 119 and 120, as their production and properties should pin down the location of the predicted superheavy Island of Stability, but 3-f ....Creating superheavy elements and isotopes. This project aims to measure properties, probabilities and timescales of competing quasifission processes, by combining Australian accelerator and detector capabilities with exotic radioactive targets. In 2015, nuclear fusion created superheavy elements with atomic numbers 113 to 118. The race is now on to create elements 119 and 120, as their production and properties should pin down the location of the predicted superheavy Island of Stability, but 3-fragment quasifission is a major impediment to their formation. This project will evaluate quassification processes on the nuclear reactions proposed to form new superheavy elements and is expected to identify the best reactions for their discovery. The synthesis of new elements tests quantum physics, relativistic chemistry and element creation in the cosmos, and offers high profile returns on investments.Read moreRead less
Moments, monopoles and the emergence of nuclear collectivity. The project aims to elucidate the origin and nature of collective nuclear vibrations. Recent evidence that vibrational nuclei might not vibrate after all has shaken the foundations of nuclear theory. This project will measure electric monopole transitions and magnetic moments to help determine these nuclei’s true nature, and expose how their collectivity emerges from the complexity of the underlying single-particle motion. The expecte ....Moments, monopoles and the emergence of nuclear collectivity. The project aims to elucidate the origin and nature of collective nuclear vibrations. Recent evidence that vibrational nuclei might not vibrate after all has shaken the foundations of nuclear theory. This project will measure electric monopole transitions and magnetic moments to help determine these nuclei’s true nature, and expose how their collectivity emerges from the complexity of the underlying single-particle motion. The expected outcome is a deeper understanding of emergent phenomena in quantum many-body systems like the atomic nucleus.Read moreRead less
Structure of Hadronic Excitations from Lattice Quantum Chromodynamics. Quantum chromodynamics describes the fundamental strong interactions between quarks and gluons as they compose hadrons such as the proton or neutron. Beyond these lowest-energy systems, the quantum mechanical excitation spectra display a rich and complex structure. Remarkably, little is known about the internal structure of these states. The central goal of this project is to unveil the nature of hadrons and their excited sta ....Structure of Hadronic Excitations from Lattice Quantum Chromodynamics. Quantum chromodynamics describes the fundamental strong interactions between quarks and gluons as they compose hadrons such as the proton or neutron. Beyond these lowest-energy systems, the quantum mechanical excitation spectra display a rich and complex structure. Remarkably, little is known about the internal structure of these states. The central goal of this project is to unveil the nature of hadrons and their excited states using the first principles approach of lattice gauge theory. By elucidating aspects of hadron structure in terms of the most fundamental non-perturbative quark and gluon fields, the project will create new knowledge impacting on renowned experimental programs at international facilities.Read moreRead less
Electromagnetic structure of hadronic excitations from lattice quantum chromodynamics. Just as quantum electrodynamics describes the quantum mechanical excitation spectra of atomic systems, quantum chromodynamics (QCD) describes the excitation spectra of quark and gluon systems, such as the proton. This project will resolve the internal structure of the low-lying excitations of QCD, as being investigated at international facilities.
Recoil spectroscopy of metastable nuclei far from stability. A unique recoil spectrometer has been developed with a sensitivity superior to competing international devices. It will be used to study the decay of long-lived states in neutron-deficient nuclei. The resulting ability to determine the quantum numbers of nuclear excited states will provide important information to test theories of nuclear matter.
The origin and evolution of heavy elements in the early universe. Everything in our Solar System, including all life on Earth, was created long ago out of material forged inside fiery stellar furnaces. The latest theoretical simulations of element production in red giant stars reveals the processes that gave us our existence, as well as help us to understand the origin of the galaxy that we inhabit.
Precision pair spectroscopy of the Hoyle state. This project aims to develop a novel new spectrometer to observe and characterise electron-positron pairs of high energy nuclear transitions with unprecedented precision. Building on unique Australian expertise and equipment, the outcomes will include new applications of electron spectroscopy to nuclear structure studies, and a better understanding of element synthesis in the universe, including the formation of 12C in the universe.

Experiments have shown major failings of our best predictive model of nuclear fusion. This project will address these failings through a multifaceted research program which will develop and benchmark an enhanced quantum model and test for missing physics by conducting precision fusion measurements for carefully chosen reactions. This project will develop a new technique that exploits fission following fusion to directly probe physical processes inside the fusion barrier, which are missing from current models. This integrated approach to fusion will allow us to better predict fusion cross sections, create new elements and exploit radioactive ion beams at new international facilities.Read moreRead less
Microscopic many-body quantum dynamics: new approaches for fundamental science and applications. A new approach to create and validate a fundamental microscopic quantum theory of interactions of composite systems, like molecules and nuclei, by exploiting ideal features of nuclear reactions such as fusion will be developed. This will have broad impact in interdisciplinary areas from astrophysics and molecular reactions to future nanotechnologies.
