Nuclear magnetism – magnetic moment measurements

A novel technique devised at ANU has recently given a breakthrough in the precision with which the magnetic moments of picosecond-lived excited states in sd-shell nuclei (i.e. isotopes of oxygen through to calcium) may be measured. A sequence of precise measurements will be performed to comprehensively test the shell model.

Nuclear collisions to probe zeptosecond quantum dynamics of the femtoworld

Fundamental concepts of quantum physics (tunnelling, entanglement, decoherence, dissipation...) are investigated in the framework of nuclear dynamics using state of the art theoretical simulation tools.

Auger electrons and X-rays from nuclear decay

The emission rate of Auger electrons and X-rays from radiosotopes are extremely important for basic science and applications, especially for medical isotopes. The project is aming to develop a new computation model.

Modelling free-ion hyperfine fields

Motivated by exciting prospects for measurements of the magnetism of rare isotopes produced by the new radioactive beam accelerators internationally, this computational project seeks to understand the enormous magnetic fields produced at the nucleus of highly charged ions by their atomic electron configuration.

Measuring exotic long-lived nuclear states in storage rings

The project aims to examine the heavy neutron-rich region of the nuclear chart. Currently, these nuclides are poorly studied, giving scope for investigations into the region. Analysing a current data set the project proposes to use Schottky Mass Spectrometry for direct mass measurements of nuclear isomeric states proving Einstein's E=mc2.

Effect on fission in deep-inelastic and transfer reactions for actinide targets

The main question that will be addressed in this project is: whether sequential fission following deep-inelastic and transfer reactions on heavy actinides populates higher-spin states in more neutron-rich isotopes compared to spontaneous fission. Data from Gammasphere experiments with heavy-actinide targets will be used for this study.

Prompt and isomeric yields in deep-inelastic and transfer reactions

Isotopic yield will be measured for deep-inelastic and transfer reactions which is used to populate neutron-rich isotopes in the A ~ 186 mass region. Experimental data from neutron-rich 186W, 187Re, and 192Os target with a 136Xe beam will be used and compared with available calculations.

Measuring free-ion hyperfine fields

This experimental project will characterize the hyperfine fields of ions emerging from target foils as highly charged ions. The data will test theoretical models we are developing, and underpin nuclear magnetism measurements on rare isotopes produced at international radioactive beam facilities such as GANIL (France), ISOLDE-CERN (Switzerland) and NSCL (USA).

Nuclear lifetimes – Doppler broadened line shape method

The measurement of the lifetimes of excited nuclear states is foundational for understanding nuclear excitations. This project will solve a current puzzle in nuclear lifetime measurements based on the Doppler-broadened line shape method and also develop a generalized analysis program for such measurements.

Crucial fundamental nuclear data for nuclear fusion and nuclear fission

Nuclear data are urgently required in national security, non-proliferation, nuclear criticality safety, medical applications, fundamental science and for the design of advanced reactor concepts (fusion, e.g. ITER), or next generation nuclear power plants (Gen IV, accelerator driven systems, ...).

Quantum vibrations in atomic nuclei

Atomic nuclei exhibit collective vibrations with various shapes which obey quantum mechanics. The study of these vibrations is fundamental to understand quantum many-body dynamics.

Theory of nuclear fission

Heavy atomic nuclei may fission in lighter fragments, releasing a large amount of energy which is used in reactors. Advanced models of many-body quantum dynamics are developed and used to describe this process.

How to create new super-heavy elements

Superheavy elements can only be created in the laboratory by the fusion of two massive nuclei. Our measurements give the clearest information on the characteristics and timescales of quasifission, the major competitor to fusion in these reactions.

Search for supernova-signatures on Earth

Detection of supernova‐produced (radio)nuclides in terrestrial archives gives insight into massive star nucleosynthesis; when and where are heavy elements formed. Direct observation of radioactive nuclides from stars and the interstellar medium would provide first experimental constraints on production rate.s We will use the most sensitive technique, accelerator mass spectrometry.

Nucleosynthesis in the laboratory - how elements are formed in stars

A fundamental scientific question is a better understanding of the elemental abundances and the isotopic pattern of our solar system which is a fingerprint of stellar nucleosynthesis. We perform nucleosynthesis in the laboratory at the ANU via a new and powerful tool, accelerator mass spectrometry, to elucidate open questions in these processes.

The triple–alpha reaction leading to the formation of stable carbon in the Universe is one of the most important nuclear astrophysical processes.  This project is aiming to improve our knowledge of the triple-alpha reaction rate from the direct observation of the electron-positron pair decays of the Hoyle state in 12C.
