Event-by-event study of neutron observables in spontaneous and thermal fission

The event-by-event fission model FREYA is extended to spontaneous fission of actinides and a variety of neutron observables are studied for spontaneous fission and fission induced by thermal neutrons with a view towards possible applications for detection of special nuclear materials.Comment: 16 pages, 24 figure

An experimental investigation of fission

Accurate measurements have been made of the average number of prompt neutrons, emitted per fission for thermal neutron fission of U233, U235, Pu239 and Pu241 and spontaneous fission of Pu240 and Pu242. The large liquid scintillator method has been used and sources of error in this method have been closely examined. In addition, precise measurements have been made of the probability distribution of neutron emission for each of the six cases above and the spontaneous fission of Cf252. The data have been compared with the neutron emission distribution calculated from fragment kinetic energy data

The physics design of the Australian synchrotron storage ring

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 development of the proposal, some background material on the Australian synchrotron research community and preliminary information on possible research programs on the new facility. The facility itself is now in the early stages of construction under the leadership of Seaborne and Jackson
