Project details

Research with exotic radioactive (unstable) nuclei, with 2-3 times more neutrons than protons is a major motivation for current international projects to develop large radioactive isotope accelerator facilities. For example in exotic 6He, two neutrons are so weakly coupled to the 4He core that their wave-function extends to 10 times the core radius (forming a "neutron-halo"). Not only can they interact with the target nucleus at much larger distances than the core, but they also interact more strongly with, and can bind more strongly to the target nucleus than to the 4He. Their (many-body) interactions with the individual nucleons of the target nucleus constitute environmental interactions and can lead to decoherence. The group's research involves experimental and theoretical investigations aimed at understanding the different interactions of stable and unstable weakly bound nuclei, using the radioactive beam capability at the ANU. A new position sensitive 512 pixel Silicon detector array has been installed to detect charged break-up fragments at backward angles. This will allow unique investigations of fragmentation of stable nuclei into alpha-particles, and studies of interactions and behaviour of radioactive nuclei.

The student has the opportunity to do hands-on developmental work and/or experiments and analysis of break-up and fusion reactions, as well involvement in theoretical modelling and simulations.
