This paper describes the physics design of the Australian Synchrotron Storage Ring—Boomerang, which is currently under construction on a site adjacent to Monash University in Melbourne, Victoria. It also includes brief historical notes on the devel

A 2D PSD based on a MWPC has been constructed for a small angle neutron scattering instrument. The active area of the detector was 640 × 640 mm2. To meet the specifications for neutron detection efficiency and spatial resolution, and to minimise par

Neutron irradiation studies of silicon and liquid phase epitaxial (LPE) GaAs Schottky barrier radiation detectors were carried out using 1.1 MeV fast neutrons produced using the Australian Nuclear Science and Technology Organisation's 3 MeV Van de Gr

The ANTARES AMS facility at the Lucas Heights Research Laboratories is operational and AMS measurements of 14C and 26Al are performed routinely. Measurement programs for a variety of other long-lived cosmogenic radioisotopes are being implemented on

The neutron capture cross section of 54 Fe has been measured with 0.2% energy resolution from 2.5 to 500 keV. A large and significant correlation is observed between the s-wave reduced neutron widths and the corresponding total radiative widths. The

The question of fine structure in the variation of the average number of prompt neutrons, ν p , emitted per fission with energy in the neutron fission of 233U and 235U has been examined. Consistent structure has been found in measurements of both ν

Pre- and post-scission neutron multiplicities have been measured as a function of fission mass-split for the reactions of 105 and 120 MeV 19 F with 232 Th. The post-scission multiplicities show no evidence for persistence of the sawtooth yield observ

A series of recent papers suggests that damping in the later stages of the fission process is weak for fission through sub-barrier states in even-even nuclei. Measurements of the number of neutrons emitted per fission for neutron fission of 230 Th ab

The fission fragment angular distributions have been measured for the neutron fission of 232 Th at a number of energies near the neutron threshold. An exhaustive search has been made for a set of transition states and barrier parameters that would si

The neutron capture cross section of 88Sr has been measured with high energy resolution between 2.5 and 400 keV using the capture cross-section facility at the 40 m station on the Oak Ridge Electron Linear Accelerator. Strong positive correlations ha
