Physics of the Nucleus

How nuclear structure influences fusion outcomes

In this project, students will explore which aspects of structure have the greatest influence on nuclear fusion probabilities near the fusion barrier.

Reactions of weakly-bound and exotic radioactive nuclei

We are developing Austalia's first high energy radioactive beam capability, and now have the world's best capability to reconstruct breakup into charged fragments

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.

Dr Cédric Simenel

Nuclear fusion and sub-zeptosecond breakup reactions

Fusion probabilities at high energies are significantly smaller than theoretical predicted, in part due to disintegration of the projectile nucleus into lighter nuclei (breakup) on timescales faster than 10-21 s. This project will help us understand these fast, complex breakup processes and their influence on fusion.

Structure of exotic nuclei far from stability studied with the SOLENOGAM spectrometer

SOLENOGAM is a new spectrometer optimised for electron and gamma-ray spectroscopy of difficult to populate nuclei that are far from stability. It will be used to investigate a variety of nuclear phenomena through coincidence spectroscopy and the measurement of internal conversion coefficients.

Transferring quantum particles

When two composite objects (molecules, atoms, atomic nuclei...) collide, they may transfer particles. Understanding how this transfer occurs in quantum mechanics is an important challenge in quantum physics.

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.

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.

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.

Nuclear lifetimes – direct timing with LaBr3 detectors

The lifetimes of excited quantum states in the atomic nucleus give extremely important information about nuclear structure and the shape of the nucleus. This project will commission a new array of of LaBr3 detectors to measure nuclear lifetimes, with the aim to replace conventional analog electronics with digital signal processing.

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.

Time correlated gamma-ray coincidence spectroscopy with the CAESAR detector array

Investigate the structure of atomic nuclei by building up the spectrum of excited states using time-correlated, gamma-ray coincidence spectroscopy.

Auger-cascade modelling for targeted cancer therapy

The emission rate of low-energy Auger electrons and X-rays from radiosotopes through the Auger cascade are extremely important for basic science and applications, especially for medical isotopes. The project is aiming to understand the nature of the Auger cascade and develop a new computational model of it for the research in targeted radioisotopes therapy.

Nuclear models in nuclear structure and reactions

Nuclei are complex quantum systems and thus require advanced modelling to understand their structure properties. This project uses such models to interpret experimental data taken at the ANU and at overseas nuclear facilities.

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.

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.

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.

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.

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).

Probing shell-model and K-isomers in the short lifetime limit

Gamma-ray transition strengths derived from the measurement of nuclear state lifetimes probe the structure of nuclear wavefunctions and hence enhance our understanding of nuclear interactions. We have developed new capabilities for short lifetime measurement at the ANU that extend our ability to probe these exotic nuclear states.

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, ...).

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.
