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
Imaging the spatial distribution of forces that bind quarks to a proton. This project will perform supercomputer simulations to resolve the distribution of forces acting on quarks inside the proton.

New knowledge will be generated in the area of fundamental strong-interaction physics by developing innovative approaches to image novel features that have not been possible in the past. The outcomes will therefore open new research possibilities by expanding the capacity of the international community to study strong interaction physics—including direct relevance to experimental research at the recently-upgraded Jefferson Lab in the US. In analogy to Rutherford's atomic model, the results will have benefit to future generations of humanity with a deeper understanding of the structure of matter.Read moreRead less
Nuclear vibrations under scrutiny in near-spherical and deformed nuclei. This Project aims to elucidate the nature of nuclear vibrations. Evidence is mounting that nuclear excitations long identified as vibrations cannot truly be so. This shakes the foundations of nuclear theory. Coulomb excitation and transfer reaction experiments are to be developed to probe the structure of these quantum states. Expected outcomes include clarification of their true nature and a deeper understanding of why nuc ....Nuclear vibrations under scrutiny in near-spherical and deformed nuclei. This Project aims to elucidate the nature of nuclear vibrations. Evidence is mounting that nuclear excitations long identified as vibrations cannot truly be so. This shakes the foundations of nuclear theory. Coulomb excitation and transfer reaction experiments are to be developed to probe the structure of these quantum states. Expected outcomes include clarification of their true nature and a deeper understanding of why nuclei differ from other many-body quantum systems that do vibrate. Anticipated benefits include enduring methodologies to facilitate international research engagement, and rigorous hands-on training in nuclear methods, to help meet Australia’s need for nuclear-qualified personnel in health, mining, industry and security.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.

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.
