Mass distribution in the reactor-neutron-induced fission of thorium-232

This investigation was undertaken to improve the data on product yields in the reactor-neutron-induced fission of /sup 232/Th. The mass distribution in the reactor-neutron-induced fission of /sup 232/Th was studied using radiochemical techniques and direct gamma-ray measurements. Absolute fission yields of the standard nuclides /sup 99/Mo and /sup 132/Te were obtained from /sup 232/Th sources irradiated in a fission counter. The yields of 36 mass chains, including three that have been measured for the first time, were determined both from measurements relative to /sup 235/U(n/sub th/, f) nth,f) yields and from /sup 232/Th data alone. 39 refs
