Measurements of the excitation energies of superdeformed states via the observation of single-step linking transitions have now been made in three even-A Pb nuclei, with a quasicontinuum analysis providing a limit in a fourth, odd-A case. These results allow us to take the first steps towards establishing systematic trends in excitation energies and binding energies in the second minimum in Pb isotopes. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]

Fragmentation reactions, typically performed at energies ∼E/A > 50 MeV, produce neutron-rich nuclei but leave little angular momentum in the residues. In this work we have examined the product distribution and angular momentum input for a 12C beam at 30 MeV/A on a thick (40 mg/cm2) target of 51V, testing the feasibility of in-beam gamma-ray spectroscopy study of target fragments at this lower energy. This technique allows the study of some neutron-rich nuclei to moderate spins, complementing the beam fragmentation studies. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]

A new recoil separator system for studying properties of isomeric states with lifetimes starting from a few hundred nanoseconds is under construction at the Heavy Ion Accelerator Facility of the Australian National University. In this contribution, the design of the system is introduced along with computer simulations on its performance and selected results from the first test measurements. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
