New technology developed by Australia, Sweden and the United States will be applied to major questions about the application of relativistic quantum mechanics to atomic structure and dynamics and spectroscopy, especially including critical issues in quantum electro-dynamics for atomic physics and applications. Discrepancies in quantum electro-dynamics have dominated international debate for decades, with claimed explanations annually failing to reveal the cause. Also a pattern of discrepancies has been seen at X-ray energies in first row metal atoms, with a similar sign and magnitude. A combined experimental an theoretical investigation will aim to reveal new light on these anomalies and serve to develop our understanding of the universe.Read moreRead less

Unique Australian experimental developments and concepts, to track the zeptosecond dynamics of fusion forming superheavy elements, have revealed unexpectedly strong quantum effects. The impact of these insights is attracting world-leaders in this vigorous field to collaborate with us. Leading an ambitious coordinated program of experiments in Australia and at big international facilities, and driving theoretical developments, this project will pin down the dynamics of heavy element formation. This will be a high-profile outcome from recent investment in Australian accelerators. Mapping out future opportunities at worldwide billion dollar accelerator developments will secure a strong Australian engagement and benefit from these massive investments.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
