Nuclear vibrations in near-spherical and deformed nuclei

This project aims to discover if the long-held concept of low-energy nuclear vibrations holds true under scrutiny from Coulomb excitation and nucleon-transfer reactions.

Ultra-fast lifetime measurements of nuclear excited states

Use ultra-fast gamma-ray detectors to perform excited-state lifetime measurements and investigate single-particle and collective features of atomic nuclei.

Nuclear batteries: Energy-storage applications of nuclear isomers

Nuclear metastable states, known colloquially as isomers, have energy densities millions of times greater than chemical batteries. This project investigates nuclear pathways for reliably extracting this energy from candidate isotopes on demand.

Exotic nuclear structure towards the neutron dripline

Investigate the properties of exotic nuclei and their impact on fundamental models and creation of the elements when stars explode.

Nuclear lifetimes - developing new apparatus and methods

The measurement of the lifetimes of excited nuclear states is foundational for understanding nuclear excitations. This project covers three measurement methods that together span the nuclear lifetime range from about 100 femtoseconds to many nanoseconds. The project can include equipment development, measurement, and the development of analysis methodology (programming and computation).

Radioimpurities in particle detectors for dark matter studies

This experiment will characterise dark matter detector material. Lowest levels of natural radioactivity in high purity samples will be analysed via ultra-senstive single atom counting using acclerator mass spectrometry.

Nuclear structure studies with particle transfer reactions

This project will use nuclear reactions to study the basic make-up of atomic nuclei at the quantum level, and investigate the impact of nuclear structure on sub-atomic forces and fundamental physics.

Measuring and 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 experimental and computational project seeks to understand the enormous magnetic fields produced at the nucleus of highly charged ions by their atomic electron configuration.

Measuring electric quadrupole moments - the shapes of atomic nuclei

New methods to determine the shapes of atomic nuclei via the measurement of their electric quadrupole moment are being developed. Most nuclei are prolate spheroids - shaped like an Australian Rules football. As well as giving a picture of the nucleus, the quadrupole moment is an important observable to test theory.

Nuclear magnetism - magnetic moment measurements

This project builds on our established track record of developing novel methods to measure magnetic moments of picosecond-lived excited states in atomic nuclei, and the theoretical interpretation of those measurements. Students will help establish new methodologies to underpin future international research at the world's leading radioactive beam laboratories.
